Top mobile app development companies for sports (August 2026 Rankings)

Buyer's GuideJul 2, 2025 · 23 min read

Short answer

Evaluating sports app development companies comes down to verifiable live production apps, event-day concurrency, and design-engineering continuity from build to launch. RaftLabs meets this bar with a hospitality platform serving 80+ properties built for the same real-time concurrency demands, 4.9/5 on Clutch across 50+ reviews, and fixed-price engagements at $29-49/hr.

Key Takeaways

  • Sports apps fail most often not at launch but at the first major event-day traffic spike. Ask every vendor specifically how they load-test against real concurrency before signing.
  • Fan engagement apps, live scoring platforms, sports betting systems, and fitness tracking apps each have fundamentally different architecture requirements. Domain depth in one category does not transfer automatically to another.
  • Premium US studios (Big Human) justify their rate when the app's interaction quality is a direct competitive differentiator. For most mid-market organizations, the same production quality is achievable at $25-$99/hr from verified studios with track records.
  • Real-time sports data integration - Sportradar, Stats Perform, official league APIs - is a technical requirement many mobile studios underestimate. Ask specifically about feed integration experience before shortlisting.
  • RaftLabs ranks second as the strongest choice for mid-market sports organizations, leagues, and fitness platforms that need a production-ready app built at a fixed price without a handoff gap.

Sports app buyers face a specific shortlisting problem. The mobile development market is large, and the majority of agencies list sports as a vertical they serve. What that claim usually means in practice is that they have built a schedules tab and a news feed. The companies that actually belong in a sports app conversation have shipped something more demanding: a live event that held up under concurrent traffic, a data feed integration that stayed accurate during a playoff run, or a fan product that users returned to between seasons rather than abandoning after the first week. According to Grand View Research, the global sports app market is projected to reach $8.03 billion by 2030, growing at a CAGR of 10.9% - a growth rate that is drawing generalist mobile agencies into the category without the infrastructure experience the vertical actually demands.

Eight companies made this list: Cubix, RaftLabs, Binary Studio, Lizard Global, NERDZ LAB, Big Human, Deltatre, and KeyToTech. RaftLabs is included because their mobile engineering team has shipped fan engagement, loyalty, and real-time apps for mid-market clients at $29-$49/hr with a Clutch rating of 4.9/5 - and the infrastructure approach behind their hospitality and retail builds is directly applicable to sports app requirements. We evaluated every company on the same criteria.

No company paid for placement on this list.

1. Cubix

Cubix is a Sunnyvale, California-based mobile app and game development company with delivery teams in Pakistan and a portfolio of more than 250 games alongside on-demand and enterprise apps for entertainment clients. Their core strength is game development and consumer entertainment apps, which is a genuine adjacency to the parts of sports that are gamified: fantasy mechanics, prediction games, second-screen engagement, and reward loops that keep fans returning between fixtures. The transfer is real, but it is a transfer - their documented depth is in games and entertainment, not in live sports data platforms, so domain fit needs to be verified during scoping.

Their team covers native iOS and Android, cross-platform builds, and backend services, with the game-engine experience that matters for any sports product leaning on real-time interaction, leaderboards, or live competition mechanics. For a sports organization building a fantasy platform, a prediction game, or a gamified fan engagement app, Cubix's 250-plus game portfolio is the relevant proof point. For a pure live-scoring or broadcast-grade streaming build, ask directly for sports references before shortlisting.

Notable work: Cubix reports a portfolio of more than 250 games plus on-demand and enterprise apps for entertainment clients. Specific sports app references are not documented in their public profile - request named sports or fantasy sports projects, and the subcategory each addressed, before shortlisting.

Pricing signal: Cubix does not publish a standard hourly rate or minimum project size. Request a written rate card and a fixed-scope estimate during scoping, and confirm which delivery location handles your engagement and how that affects timeline and cost.

What to watch: Cubix's documented specialty is game and entertainment app development rather than live sports data infrastructure. That is a strong fit for gamified and fantasy sports products and a weaker one for real-time scoring or streaming platforms. Verify sports-domain depth and event-day concurrency experience directly before committing.

  • Best for: Sports organizations building fantasy platforms, prediction games, or gamified fan engagement apps that draw on game-development experience

  • Specialization: Mobile game development, cross-platform and native iOS and Android apps, on-demand and entertainment apps

  • Pricing: Not publicly listed - request a rate card and fixed-scope estimate

  • Clutch: Clutch profile listed; confirm rating before engaging


2. RaftLabs

RaftLabs is a mobile app development studio for mid-market clients. Their mobile team handles React Native and native iOS and Android builds with in-house backend engineering, sports data API integration, and post-launch support. Their positioning in sports is not as a sports-exclusive studio but as a production engineering partner for companies building fan engagement apps, real-time mobile platforms, and loyalty mechanics in verticals where event-day performance and sustained retention are non-negotiable requirements.

What they bring to sports specifically is a backend and infrastructure approach that their adjacent delivery history demonstrates directly. A hospitality management platform serving 80+ properties handles real-time service requests, concurrent mobile sessions, and push notification delivery at scale - the same concurrency engineering that a live sports event demands. A loyalty platform for a multi-brand retail operator handles real-time points mechanics and personalized push triggers across iOS and Android - the same architecture as a fan rewards app. The underlying engineering is the same. The sports domain is the context layer.

Notable work: RaftLabs built a hospitality management platform serving 80+ properties with real-time service requests, mobile check-in, and guest engagement features that required the same concurrency architecture as a live sports event. A loyalty and personalization platform for a multi-brand retail operator covers real-time points mechanics, push-triggered personalization, and account management across iOS and Android. A remote patient monitoring app handles real-time data ingestion across 80+ clinical sites - infrastructure directly analogous to multi-venue sports data collection.

Pricing signal: $29-$49/hr. A production mobile app with real-time data integration, push notification infrastructure, and full backend services typically runs $50K to $150K depending on scope. Fixed-price with milestone payments agreed before any build starts, with a two-to-four-week scoping phase before commitment.

What to watch: RaftLabs is a 60-person firm. Enterprise sports programs requiring parallel engineering workstreams, simultaneous multi-league integrations, or a team of 20 or more engineers on a single program exceed their operational scale. What they do consistently well: accountable mid-market mobile builds for sports organizations with a defined scope, delivered by a team that handles design, engineering, and launch under one engagement.

From the field: The most common mistake sports organizations make when evaluating mobile development partners is judging agencies on their sports portfolio rather than their infrastructure approach. A sports app that holds up at 9:00 PM on championship night is not a design achievement. It is an architecture achievement. Ask every vendor you consider to walk you through how they handle event-day concurrency, push notification batching under load, and real-time feed failover before evaluating a single screen.

  • Best for: Mid-market sports organizations, regional leagues, fitness platforms, and fan engagement products with a budget of $50K-$200K needing one accountable team

  • Specialization: Fan engagement apps, real-time mobile infrastructure, loyalty and rewards platforms, React Native and native iOS and Android

  • Pricing: $29-$49/hr, fixed-price engagements from $50K

  • Rating: 4.9/5 (Clutch, 50+ reviews)


3. Binary Studio

Binary Studio is a boutique software development company headquartered in Lviv, Ukraine, with a US presence in San Francisco and named practices in both legaltech and sports app development. Unlike the many generalist agencies that list sports as one vertical among dozens, Binary Studio maintains sports as a declared specialty alongside its legaltech case-management and eDiscovery work, which is a stronger starting signal than an undifferentiated services menu. As a boutique firm, they position on engineering quality and a small senior team rather than scale.

Their engineering covers web and mobile builds with backend services, and the boutique model means the same senior engineers who scope the work tend to deliver it - useful continuity for a sports product whose requirements shift across a season. For a mid-market sports organization that values a small, senior team over a large offshore roster, Binary Studio's declared sports practice makes them worth a conversation. Ask for the specific sports apps behind the practice - live scoring, fan engagement, fitness - to confirm the depth matches your subcategory.

Notable work: Binary Studio lists sports app development as a named practice alongside legaltech case management and eDiscovery. Specific sports app references are not documented in their public profile - ask for named live production sports apps, and the subcategory each addressed, before shortlisting.

Pricing signal: Binary Studio does not publish a standard hourly rate. Request a written rate card and a bounded estimate during scoping. As a boutique firm, confirm team size and availability against your timeline early, since senior capacity is the constraint that matters most here.

What to watch: Binary Studio is a boutique studio, which is a strength for senior-led engineering and a constraint for large or time-critical programs that need a team of ten or more engineers at once. Their sports practice is declared rather than extensively documented in public - verify the live sports apps behind it before committing.

  • Best for: Mid-market sports organizations wanting a small, senior engineering team with a declared sports app practice

  • Specialization: Sports app development, legaltech (case management, eDiscovery), web and mobile engineering

  • Pricing: Not publicly listed - request a rate card and confirm team availability

  • Clutch: Clutch profile listed; confirm rating before engaging


4. Lizard Global

Lizard Global is an Amsterdam-based mobile and web development studio with 70 Clutch reviews at 5/5 - one of the highest verified review counts on this shortlist. Their mobile team covers React Native, native iOS and Android, and full backend development. Their sports industry work includes fitness apps and sports technology platforms built for European and US clients. At $50-$99/hr, they sit in a mid-range tier that combines verified delivery track record with a price point well below the premium US studios.

Their approach combines product strategy, UX design, and engineering under one studio. Client feedback across their 70 Clutch reviews consistently highlights technical quality, adaptability when requirements evolve, and delivery reliability - the combination that matters most for a sports platform where the event calendar is fixed and the launch date is not negotiable.

Notable work: Lizard Global has built mobile apps and digital platforms for sports technology clients across Europe and the US, including fitness and athlete performance applications. Their review depth across 70 clients reflects consistent delivery rather than standout single projects, which is the more meaningful signal for a studio you plan to work with through a full product lifecycle.

Pricing signal: $50-$99/hr. Minimum project $10,000. Engagements typically run $30K to $200K. Amsterdam-based with English-first delivery - no communication friction for US, UK, or Australian clients working across time zones.

What to watch: Lizard Global performs best on engagements where the product direction is defined and the scope is bounded. Open-ended programs requiring extensive upstream sports domain strategy or niche integrations with proprietary league data systems may benefit from involving a sports technology consultant for the upstream definition before engaging Lizard Global for the build.

  • Best for: Mid-market sports technology companies and organizations in Europe and the US needing verified mobile delivery at a mid-range price point

  • Specialization: Mobile app development, sports tech platforms, fitness applications, React Native and native iOS and Android

  • Pricing: $50-$99/hr, minimum project $10K

  • Rating: 5/5 (Clutch, 70 reviews)


5. NERDZ LAB

NERDZ LAB is a mobile and web development studio based in Lviv, Ukraine, with 50 Clutch reviews at 5/5 and a rate card of $25-$49/hr. Their sports industry portfolio includes Android and iOS app development for sports technology startups. Client feedback consistently highlights technical execution quality, on-time delivery, and communication depth - a combination that is less common at this price point than the rate card would suggest. For sports organizations with tighter budgets that still need verified technical delivery, NERDZ LAB is the accessible end of this shortlist without sacrificing the review depth that separates accountable studios from untested ones.

Their mobile development covers native and React Native builds with integrated backend services. Their Clutch record includes sports technology startup work, which means they have navigated the specific challenge of building a sports product for a client who is simultaneously figuring out their own product market fit.

Notable work: NERDZ LAB has built Android and iOS apps for sports technology clients, including startups in the sports performance and fan engagement space. Their work covers native Android development for sports technology companies and React Native builds for sports-adjacent fitness and wellness applications.

Pricing signal: $25-$49/hr. Minimum project $5,000. One of the most accessible options on this shortlist for a sports organization that needs a verified track record at a budget that rules out the mid-tier US and European studios.

What to watch: NERDZ LAB is best suited for single-app builds with a clear and bounded scope. Multi-platform, multi-sport, or enterprise-scale programs requiring teams of 10 or more engineers simultaneously are better served by a larger studio. Their communication quality is strong, and the Ukraine-based team works best with clients who can provide clear written specifications and participate in structured sprint reviews. The 50-review Clutch record at a perfect rating is the strongest quality signal at this price point.

  • Best for: Sports tech startups and budget-conscious sports organizations building a focused app with a defined scope and a budget under $80K

  • Specialization: Native Android and iOS development for sports tech, React Native, sports performance and fan engagement apps

  • Pricing: $25-$49/hr, minimum project $5K

  • Rating: 5/5 (Clutch, 50 reviews)


6. Big Human

Big Human is a New York-based digital product studio that builds consumer apps and brands for startups and media and entertainment clients. Their portfolio includes work with Netflix, Rockefeller Center, and HQ Trivia - the last of which is directly relevant to sports, because HQ Trivia was a live, synchronized, high-concurrency event app where large numbers of users participated in the same real-time moment. That is the same architectural problem a live sports app faces on event day, which makes Big Human one of the few consumer studios on this list with a documented live-concurrency credential.

Their team covers product strategy, brand, UX and UI design, and native and cross-platform engineering, with a consumer polish that suits fan-facing and media-adjacent sports products. For a sports organization building a consumer fan app, a live second-screen experience, or a media property where brand and interaction quality are the product, Big Human's entertainment portfolio and live-event experience are the relevant proof. For a backend-heavy sports data platform or an enterprise league management tool, the fit is weaker - their documented strength is consumer product and brand.

Notable work: Big Human has built consumer products and brands for Netflix, Rockefeller Center, and HQ Trivia. The HQ Trivia work is the most sports-relevant: a live, synchronized game app that handled large numbers of concurrent users in a single real-time event, the same concurrency challenge a live sports app faces on event day.

Pricing signal: Engagements are reported in the $500K to $1M-plus range per third-party listings - premium consumer studio territory. Confirm the current rate card and minimum project size directly, and match it against a budget calibrated for a high-end consumer build rather than a mid-market one.

What to watch: Big Human's documented strength is consumer product design and brand for media and entertainment. Pure sports data platforms, live scoring infrastructure, or enterprise league tools are less represented in their public work. The engagement size also places them at the premium end - appropriate when consumer quality is the product, oversized when the challenge is backend architecture.

  • Best for: Consumer fan apps, live second-screen experiences, and sports media brands where product design and live-event concurrency are the priority

  • Specialization: Consumer product design, brand, native and cross-platform apps, media and entertainment

  • Pricing: Reported $500K-$1M+ per third-party listings - confirm directly

  • Clutch: Clutch profile listed; confirm rating before engaging


7. Deltatre

Deltatre is a sports and media technology company with headquarters in Turin, Italy, and London, UK. It builds enterprise-grade products for the sports and entertainment industry: OTT streaming platforms (Vesper), digital fan-engagement software (Forge), and broadcast graphics systems used across live sports and media. Its position on this list is different from the agencies around it - Deltatre is a product and platform technology vendor for large rights holders and broadcasters, not a per-project custom mobile development shop.

That distinction matters for how you would engage them. If you are a league, federation, broadcaster, or major rights holder that needs an OTT streaming or fan-engagement platform at scale, Deltatre's products and delivery experience are directly relevant. If you are a mid-market sports organization or startup looking for a team to build a bespoke app from a blank sheet at a mid-market budget, an enterprise platform vendor is likely more than the brief requires - confirm the engagement model and minimums before shortlisting.

Notable work: Per the company's own site, Deltatre powers streaming and digital experiences for major properties including the NFL, NHL, MLB, UFC, and BritBox, among other leagues and broadcasters. These are enterprise streaming and fan-platform engagements rather than mid-market custom app builds; treat them as evidence of large-scale live-media capability rather than small-team app delivery.

Pricing signal: Deltatre does not publish pricing. Engagements are enterprise and project-based; request a quote scoped to your platform, audience scale, and integration requirements.

What to watch: Deltatre is a platform and product provider for enterprise sports and media clients rather than a bespoke dev shop - a fit if you want to build on their OTT and fan-engagement products at broadcaster scale, less so if you need a small, fully custom app on a mid-market budget. Confirm the engagement model, minimum project size, and how much of the work is product configuration versus custom development before committing.

  • Best for: Leagues, federations, broadcasters, and major rights holders needing enterprise OTT streaming or fan-engagement platforms at scale

  • Specialization: OTT streaming platforms, digital fan engagement, broadcast graphics for sports and media

  • Pricing: Not publicly listed - enterprise project-based, request a quote

  • Rating: Profile listed; confirm before engaging


8. KeyToTech

KeyToTech is a London-based mobile development studio with 17 Clutch reviews at 5/5 and a primary focus on mobile app development, which represents roughly half of their work. Their hourly rate of $25-$49/hr is notably accessible for a London-based firm, making them a practical option for UK sports organizations that want a locally based development team without the premium rate card of most UK-headquartered studios.

Their mobile portfolio covers iOS, Android, and cross-platform development with backend integration. Approximately 90% of their Clutch reviewers specifically call out responsiveness, flexibility under changing requirements, and the ability to deliver complex digital products - feedback patterns that matter for sports apps where the product requirements evolve through the season.

Notable work: KeyToTech has delivered mobile apps for sports technology clients and built complex digital products for clients in regulated and technically demanding verticals. Their mobile development work includes applications requiring real-time data integration and multi-platform delivery, which are the core technical requirements for a sports platform.

Pricing signal: $25-$49/hr. Minimum project $10,000. A strong value option for UK and European sports organizations that want a London-based team at a rate well below the typical UK studio premium.

What to watch: With 17 Clutch reviews, KeyToTech's verified track record is shorter than most studios on this list. Request specific references in the sports or sports technology category before committing. A capacity conversation early in the evaluation is worthwhile - team size limits how quickly they can scale up on a large or time-critical engagement.

  • Best for: UK and European sports organizations wanting a London-based mobile development team at an accessible price point

  • Specialization: Mobile app development (iOS, Android, React Native), sports tech applications, complex digital products

  • Pricing: $25-$49/hr, minimum project $10K

  • Rating: 5/5 (Clutch, 17 reviews)

The question that separates the right sports app company from the wrong one

The most common misalignment in sports app procurement comes from treating sports app development as a single category. There are three meaningfully different things a sports organization might be building, and they require different studios:

Fan content and engagement apps are the largest subcategory - apps that deliver scores, schedules, news, social content, team updates, and loyalty mechanics to an existing fan base. The primary technical requirements are push notification infrastructure, content management flexibility, and engagement mechanics that produce return sessions between events. Big Human, Lizard Global, and RaftLabs are strong choices here.

Live data and real-time platforms - sports betting apps, live fantasy scoring, play-by-play applications, and second-screen experiences - require a different architecture. Feed latency management, real-time database design, concurrent session handling at event-day scale, and graceful degradation when a data source fails are the engineering challenges. Deltatre brings enterprise live-streaming and second-screen fan-platform experience here; Cubix, RaftLabs, and NERDZ LAB bring adjacent real-time and game-engine infrastructure experience.

Performance and fitness apps - athlete tracking, coaching analytics, training load monitoring, wearable integration - are primarily a data and sensor integration challenge. The UX requirements are distinct from fan-facing apps. KeyToTech's technical depth is the stronger fit in this subcategory. None of the remaining studios specializes primarily in performance and fitness, so verify sensor and wearable depth directly before shortlisting for this category.

Getting the subcategory right before evaluating vendors eliminates most shortlist mismatches.

"In the digital economy, sports is the last truly live content. The people who understand that at the technical level build very different infrastructure than the people who build news apps." - Wilson White, Head of Government Affairs and Public Policy, Google (on sports streaming infrastructure requirements)

According to Deloitte's 2024 Sports Industry Outlook, sports technology investment surpassed $12 billion globally, with mobile fan engagement platforms representing the largest single category of sports tech spending. The same report found that the apps with the highest Day-30 retention rates - above 35% in a category where 20% is the median - shared three characteristics: real-time data that was accurate within seconds of the live event, push notification relevance calibrated to individual fan behavior, and offline-first architecture that kept the core experience functional in stadium environments with limited connectivity. Those are engineering decisions made in the first four weeks of a project, not design decisions made in the last four.

The verdict

The right sports app development company depends entirely on what you are building and what your budget requires.

For sports organizations building fantasy platforms, prediction games, or gamified fan engagement: Cubix. A portfolio of more than 250 games is a genuine adjacency for any sports product built on live competition mechanics - verify the sports references and confirm pricing before shortlisting.

For mid-market sports organizations, regional leagues, and fan engagement platforms that need one accountable team at a fixed price: RaftLabs. $29-$49/hr, 4.9/5 Clutch, real-time infrastructure experience, and design to launch without a handoff gap.

For mid-market sports organizations that want a small, senior engineering team with a declared sports practice: Binary Studio. The boutique model favors engineering quality over scale - confirm the live sports apps behind the practice and the team's availability against your timeline.

For European and international sports tech companies wanting verified mid-range delivery: Lizard Global. Seventy Clutch reviews at 5/5 is a track record most studios cannot match.

For sports tech startups with a focused scope and a budget under $80K: NERDZ LAB. Fifty reviews at 5/5 at $25-$49/hr is the strongest accessible option on this list.

For consumer fan apps, live second-screen experiences, and sports media brands: Big Human. Their work with Netflix, Rockefeller Center, and the live concurrency of HQ Trivia is the relevant credential - confirm the engagement size fits a premium consumer budget.

For leagues, broadcasters, and major rights holders that need an enterprise OTT streaming or fan-engagement platform at scale: Deltatre. Their products power streaming and digital for major leagues - confirm the enterprise engagement model fits your scope and budget.

For UK and European sports organizations wanting a London-based team at an accessible price point: KeyToTech. Their rate is well below what London studios typically charge, and their 5/5 Clutch rating holds across 17 verified reviews.

The mistake most sports organizations make is evaluating development partners on their design portfolio and discovering the infrastructure gap after the contract is signed. Diagnose the technical requirements - concurrency, data feeds, push infrastructure - before evaluating a single screen.

Frequently asked questions

A basic sports app with live scores, team schedules, and push notifications costs $25,000 to $60,000. A mid-range fan engagement platform with personalization, in-app purchases, and social features costs $60,000 to $150,000. A full-scale platform with live streaming, real-time betting integration, fantasy league mechanics, and multi-sport data feeds costs $150,000 to $500,000 or more. The biggest cost variables are sports data feed licensing and integration complexity, the number of supported sports and leagues, and whether the build uses native iOS and Android or a cross-platform framework. RaftLabs provides fixed-price proposals after a two-to-four-week scoping engagement.
A focused MVP for a single sport - live scores, schedule, basic fan features - takes ten to sixteen weeks with a disciplined team. A mid-range fan engagement platform with personalization and social features takes sixteen to twenty-four weeks. A full-scale platform with live streaming, betting integration, and fantasy mechanics takes six to twelve months. Timeline is most affected by third-party data feed integration complexity, the number of sports data sources, and how quickly your internal team can review and approve builds at each milestone.
Look for three things: live production apps in the Sports or Health and Fitness category with verifiable App Store and Play Store ratings; direct experience with sports data feed APIs (Sportradar, Stats Perform, Opta, or official league APIs); and a clear approach to real-time infrastructure, push notification delivery at event-day scale, and offline-first architecture for stadium environments with poor connectivity. An agency that has built for other verticals but never handled a live sports event is taking on an architecture challenge they may not have encountered before. When you check a candidate's app store listing, read the most recent negative reviews specifically - they reveal what breaks under real usage more honestly than the star average. And ask directly how they handle push delivery when a stadium has poor cell coverage: local notification fallbacks, pre-event content caching, or beacon-triggered local pushes are the specific techniques that separate real stadium experience from theory.
For most mid-market sports organizations, React Native or Flutter delivers a high-quality app on both iOS and Android at significantly lower cost and faster timeline than dual native builds. Pure native Swift and Kotlin is worth the premium when the app depends on hardware features - camera, augmented reality, Bluetooth beacon integration for stadium wayfinding - that cross-platform frameworks still handle imperfectly. Most fan apps, live score platforms, and fitness tracking apps build well on React Native. Live AR overlays, hardware-integrated wearables, and near-native game mechanics are the cases where native justifies its cost.
RaftLabs builds mobile apps for mid-market clients at $29-$49/hr with fixed-price engagements. Their mobile portfolio spans fan engagement platforms, loyalty and rewards apps, and real-time mobile products for clients in hospitality, retail, and health sectors - all requiring the same concurrency engineering and real-time infrastructure as a live sports platform. They work on React Native and native iOS and Android, with in-house backend engineering, API integration, and post-launch support. 4.9/5 on Clutch. If you need an accountable team that handles design, engineering, and launch without a handoff gap, RaftLabs is worth a scoping conversation.
The main commercial providers are Sportradar, Stats Perform (which absorbed Opta), and for US markets the official league APIs from the NFL, NBA, MLB, and MLS. Fantasy sports engines often use proprietary feeds alongside these. Ask any development company which feeds they have integrated, how they handle feed latency during live events, and how they structure the app to degrade gracefully when a data source is delayed or unavailable. Push for the specific endpoints they consumed and the edge cases they handled - a vague reference to general REST API experience is a tell. This question cleanly separates companies that have shipped live sports apps from those that have not.
Ask for specific numbers: peak concurrent user count, how the backend was architected to handle it, and what the fallback was when a third-party data feed went down mid-event. A team that has genuinely shipped a live sports app has a specific story. A team that hasn't will give a general answer about scalable cloud infrastructure and auto-scaling policies - the correct vocabulary, but not the same as having lived through a real event.
A sports app launch isn't the end of a project, it's the start of a production relationship that runs through an entire season calendar. Ask who handles incident response if the app fails during a match, what the SLA is for a P1 incident during a live event, and whether the team that built the app is the one maintaining it or whether it hands off to a separate support team. Vendors with a real post-launch sports model answer immediately; the ones who haven't thought it through promise responsiveness and stay vague on specifics.
