Trusted by
RaftLabs is a mobile app development company that has shipped 50+ iOS and Android apps since 2020 for businesses across retail, hospitality, healthcare, and logistics. We're a tech studio, not an agency. One team handles design, build, and App Store delivery with no handoffs between vendors. Businesses come to us when their mobile situation is costing them users. Not always dramatically: sometimes it's a slow app that looks embarrassing next to competitors, sometimes it's no app at all while mobile traffic climbs. Either way, we scope what needs to be built and ship it in 8--14 weeks at a fixed price.
Mobile services
iOS apps
Flutter covers the full iOS feature set for most builds: App Store delivery, Face ID, push notifications, in-app purchases, and Apple Watch extensions. We reach for Swift and SwiftUI when the product genuinely needs ARKit, Core ML, or HealthKit depth that cross-platform cannot access.
Android apps
Flutter and React Native handle the full Android feature set for most business apps: Google Play delivery, background services, push notifications, Bluetooth and NFC. We reach for Kotlin when the product needs hardware-level integrations or custom Android platform APIs.
Cross-platform apps
React Native and Flutter for iOS and Android from one codebase. Near-native performance, shared business logic, and 60--70% of the cost of two separate native builds. The right choice for most business apps.
Offline-first mobile apps
Apps that work in areas with no connectivity -- field service, warehouse, inspection, and logistics tools. Data syncs when the connection returns, with conflict resolution built into the architecture from day one.
B2B and enterprise mobile tools
Internal tools that replace the spreadsheet or the paper form: inventory apps, field service apps, sales enablement apps, and approval workflows. Built for how your team actually works, not a generic template.
Mobile app migration and rebuilds
If your existing app is slowing you down, we audit it, document what exists, and rebuild it properly. We've migrated legacy Objective-C codebases to Swift, and legacy Java Android apps to Kotlin, without losing production data or user history.
AI features in mobile
On-device AI inference, conversational AI integrated into app flows, and RAG-backed search that queries your own data. AI features scoped into the build, not retrofitted after launch.
Clients
Founders launching their first app
You have validated demand and users ready to sign up. We scope exactly what to build for launch, not a full-featured v2, and deliver to the App Store and Google Play in 8--10 weeks. Fixed price. No surprises.
Businesses adding a mobile channel
Your product works on desktop and your users expect mobile. We build the iOS and Android app alongside your existing system without disrupting what is already running. New mobile users are on the app within 10--12 weeks.
Teams rebuilding an outdated app
Your current app is slowing every release and embarrassing your sales team. We audit what exists, document what matters, and rebuild it properly. No data loss, no production regression. Legacy Objective-C and old React Native codebases are not new to us.
Agencies and product teams
You have a client who needs a mobile app and need a reliable delivery partner. We work named or white-label. Your client relationship, our design, build, and App Store delivery.
The process
We spend the first week mapping user flows, data models, and third-party integrations. You get a fixed-price scope document -- not a vague estimate -- before we write a line of code. Every edge case, every API dependency, every platform-specific consideration is documented.
We design every screen in Figma, including empty states, error states, and loading states. You see the full product before we build anything. Changes at this stage are cheap. Changes during development are not.
Development runs in two-week cycles. You get a working build every two weeks -- not a status report, a real app you can install and test. Backend API, authentication, core flows, integrations, and push notifications all ship before polish.
We test on real devices, not just simulators. The QA phase covers functional testing, performance testing, offline behaviour, and edge cases. We fix everything before submission.
We handle Google Play and App Store submission including screenshots, metadata, privacy policies, and age ratings. We budget for one review cycle with Apple. You receive full source code, documentation, and app store credentials.
Tell us what you're building. We'll tell you what it costs and how long it takes -- before any commitment.
Why us
You get a scope document with every feature, edge case, and third-party dependency listed and priced before we write a line of code. No retroactive billing, no "that was out of scope" conversations after launch.
That volume means we've already solved the problems your build will hit: App Store rejection patterns, offline sync conflicts, push notification delivery rates. We've been through them.
One codebase, both stores, faster delivery. We reach for Swift or Kotlin only when your product genuinely needs platform-exclusive APIs. You get an honest recommendation, not whichever fills more of our time.
We test on real hardware, not simulators. QA covers functional testing, performance under realistic data loads, offline behavior, and edge cases. We fix everything before submission.
You receive the complete source code, documentation, and app store credentials when the project closes. No proprietary runtime, no platform lock-in. Your code is yours.
Single core workflow, authentication, push notifications, App Store delivery: shipped in 8--14 weeks. We achieve this through tight scoping upfront and two-week milestone builds, not status reports.
Why us
The engineers who assess your mobile app requirements also build it. No handoff to a junior team after the contract is signed. The same person who demos the prototype handles the App Store submission.
We scope the app, calculate the cost, and lock it in writing before development starts. A scope change is a change request: priced and agreed before work begins.
Clients include Vodafone, Nike, and Aldi. A community event app we built reached 50,000 users within 6 months of launch. A B2B food management platform tripled operator revenue in 30 days.
Eight weeks of bug fixes, performance tuning, and App Store update management after launch — included in the project price, not sold as a separate retainer.
What clients say
Three-year average engagement. Founders and operators describing the work in their own words. No marketing varnish.
IrelandWorking with RaftLabs has been amazing. The team is super responsive and quick to address our needs. They built a booking platform that's been a game changer for our team and our guests.

A focused mobile app -- core user workflow, push notifications, authentication, and app store delivery for iOS and Android -- typically runs $25,000--$60,000. A more complete build with complex backend integration, real-time features, payments, and offline capability runs $60,000--$130,000. Consumer apps with complex UI and media features run higher. We scope every project before pricing it. You get a fixed cost before development starts, not a variable estimate.
Most focused mobile apps deliver in 8--14 weeks from scope sign-off. A cross-platform app (iOS and Android from one codebase) for a single core workflow typically delivers in 8--10 weeks. A native iOS and Android build with a custom backend API typically takes 12--16 weeks. Apps with real-time features, complex data sync, or regulated compliance requirements take longer. We give you a fixed timeline when we scope the project.
Cross-platform is our default. Flutter and React Native give you iOS and Android from one codebase at 60--70% of the cost of two separate native builds, with near-native performance that is good enough for almost every business app. We reach for Swift (iOS) or Kotlin (Android) only when your product genuinely needs platform-exclusive APIs -- ARKit, Core ML, HealthKit, Android hardware APIs, or custom Bluetooth integrations. We tell you which is right before we scope, not after we've started.
Yes. We build on-device inference with Core ML (iOS) and TensorFlow Lite (Android), integrate AI APIs like OpenAI or Anthropic for in-app chat and content generation, and build RAG-backed search that queries your own data. AI features are scoped into the initial build rather than bolted on later. Most AI features add 2--4 weeks to the project timeline.
We hand over full source code, app store credentials, and documentation. We offer a support and maintenance retainer for ongoing bug fixes, OS compatibility updates, and minor feature additions. If you want to extend the app significantly after launch, we scope that as a new project. We don't lock clients into proprietary platforms -- your code is yours.
We've shipped mobile apps across healthcare (HIPAA-compliant telehealth and remote patient monitoring), hospitality (booking platforms and mobile check-in), logistics (driver apps and delivery tracking), retail (shopping and loyalty programs), and social commerce. More than 60 apps shipped since 2020. If your industry has a workflow that belongs on a phone, we've likely built something close to it.
