Fintech mobile app development that converts users, not loses them at step three.
We build iOS and Android apps for fintech companies, neobanks, payment platforms, lending products, and financial services businesses. PCI-DSS payment handling, biometric authentication, real-time transaction feeds, open banking integrations, and KYC onboarding flows - designed to convert users, not lose them at step three. Our fintech clients come to us because their last mobile build felt like a 2015 banking portal. We build apps that work the way users expect: fast, secure, and finished in 8-14 weeks at a fixed price.
PCI-DSS compliant payment handling by default - card data never touches your server unencrypted
Biometric authentication with Face ID, Touch ID, and Android fingerprint from day one
Open banking connections via Plaid, TrueLayer, and MX - account aggregation, balance reads, and payment initiation
KYC onboarding flows that complete in under 3 minutes - ID capture, liveness check, and AML screening in one sequence
Real-time transaction feeds and push alerts for spend and balance events
Fixed price and timeline agreed before development starts - 8-14 week average delivery

Open banking integrations use Plaid, TrueLayer, and MX for account aggregation and payment initiation.
Biometric authentication with Face ID, Touch ID, and Android fingerprint is included from day one.
A UAE POS app delivered by RaftLabs reached 5,000+ downloads and a 4.8 Google Play rating within 3 months of launch.
Trusted by
Forty percent of signups quit before they fund the account.
A user downloads your neobank app, ready to move money. Then the KYC flow starts: eight steps, an ID photo that gets rejected twice, a liveness check that stalls, a set of security questions. By step three they close the app and never come back.
None of that was a bug. It was a compliance requirement nobody scoped upfront, so it landed late and shipped clumsy. The onboarding became the product, and nobody designed it like one.
Onboarding is the first thing your user experiences. Build it like the last thing that should ever lose them.
According to McKinsey's 2023 report "Fintechs: A New Paradigm of Growth," fintech revenue is projected to grow at 15% annually from 2023 to 2028, three times the rate of traditional banking. For neobanks, payment platforms, and lending products, that growth makes the quality of the mobile experience a direct competitive advantage: users who find onboarding slow or compliance flows clunky simply move to a better-built rival.
We build iOS and Android apps for fintech companies, neobanks, payment platforms, and lending products, with PCI-DSS, KYC, AML, and GDPR controls designed into the architecture before the first line of code, not bolted on before launch. A mobile POS app we built for a UAE fintech reached 5,000+ downloads, a 4.8 Google Play rating, and 10,000+ transactions in its first 3 months of operation, with the compliance architecture agreed with the client's legal team before a line of code was written. The team that scopes your compliance architecture is the team that builds the app and handles the App Store submission, so nothing gets lost in a handoff. See our full scope of work across payments, lending, and neobanking.
This pays off when compliance and conversion both have to be right.
Everything on the left should already be true for your product. Even one thing on the right, and a fixed-scope mobile build isn't the smartest next step yet.
A fit
01
A fintech product (neobank, payment platform, lending, or wealthtech) that needs iOS and Android in users' hands, not a web portal.
02
Compliance is non-negotiable: PCI-DSS, KYC, AML, or open banking data that has to be handled correctly from day one.
03
Budget for a fixed-scope build from $35,000, and a decision-maker who can approve the compliance architecture.
Not a fit
A pre-revenue idea with no regulatory scope defined and requirements still forming.
A simple marketing or content app with no payment, account, or financial data handling.
Shopping for the cheapest hourly team rather than a fixed-scope partner.
Balance and transaction data from multiple banks in one view via Plaid, TrueLayer, or MX. Account verification for ACH setup. Payment initiation for account-to-account transfers. Permissioned data sync respects user consent at each connection.
Portfolio dashboards, real-time price feeds, trade execution flows, and performance analytics. Secure document storage for statements and tax reports. Multi-currency support and FX rate display.
ID document capture, liveness detection, identity verification, AML screening, and risk-tiered review queues. Designed to complete in under 3 minutes for standard users. Instrumented to show exactly where users drop off.
Walk us through your onboarding flow, compliance needs, and target markets. We'll tell you how we'd build it and what it costs, with a compliance architecture outline to follow.
How it works
From scope to the App Store
Week 1
01
Compliance and product scoping
We map every user journey, third-party integration, and data flow. You leave week one with a written scope, a PCI-DSS or regulatory compliance architecture document, an integration assessment for your open banking or KYC provider, and a fixed-price quote.
Weeks 2-3
02
Security architecture and design
Authentication flows, data encryption, tokenization, and session management are designed before code is written. Every screen is wireframed and reviewed with your product and compliance leads. Figma files show how sensitive data is accessed, displayed, and protected at each step.
Weeks 4-12
03
Build, integrate, and QA
Bi-weekly sprint delivery. A working build on TestFlight and Android beta from sprint one. Penetration testing and compliance checks run in parallel with development - not as a phase at the end. Third-party integrations are tested against sandbox environments before any production credentials are used.
Weeks 12-14
04
App Store submission and launch
We handle App Store and Google Play submission including financial app metadata, privacy nutrition labels, and age rating documentation. Source code, compliance documentation, API credentials, and app store accounts are transferred to your team at launch.
What fintech mobile app development costs
We price by project, not by the hour. After a scoping session you get a fixed quote with a defined scope, a compliance architecture, and a price, so you know the number before development starts. Where you land depends on scope, not negotiation:
Focused fintech app, $35,000-$60,000
Account dashboard, transaction feed, push notifications, and biometric login. Ships in 8 to 10 weeks.
With open banking, $50,000-$80,000
Adds account aggregation, balance reads, and payment initiation via Plaid, TrueLayer, or MX. A neobank MVP ships in 12 to 14 weeks.
Full neobank, $80,000-$150,000
Card issuance, KYC, virtual accounts, and lending with credit decisioning. A lending build runs 14 to 16 weeks.
What it costs
Fixed price, agreed before development starts.
A defined scope, a compliance architecture, and a number, before any code is written.
$35,000-$150,000
Fixed cost by project. 8-14 week average delivery. The total is agreed before development starts, not an estimate with a flexible ceiling.
Compliance requirements are scoped upfront, so they don't surface late and delay the build by three months at the end.
Fixed price
We scope the app, calculate the cost, and lock it in writing. A scope change is a priced change request, agreed before work begins. We never absorb changes into the project silently.
Post-launch support
8 weeks of post-launch support included in the project price: bug fixes, OS compatibility updates, and performance tuning, with on-call availability during the critical first 30 days. No separate retainer required.
A focused fintech app - account dashboard, transaction feed, push notifications, and biometric login - typically runs $35,000-$60,000. Add open banking integration via Plaid or TrueLayer and you're looking at $50,000-$80,000. A full neobank with card issuance, KYC, virtual accounts, and lending features sits in the $80,000-$150,000 range. The fixed total is agreed before development starts, not an estimate with a flexible ceiling. Request a 30-minute call to get a number for your specific scope. Our portfolio includes a UAE POS app with 5,000+ downloads and a 4.8 Google Play rating, and a neobank MVP delivered to the App Store in 12 weeks.
Most fintech mobile apps ship in 8-14 weeks. A payment app with card acceptance, real-time reporting, and a merchant dashboard typically delivers in 8-10 weeks. A neobank MVP with KYC, account management, and open banking integration takes 12-14 weeks. A lending app with credit decisioning and repayment management runs 14-16 weeks. Every project begins with a one-week discovery session that defines the exact scope, compliance architecture, and third-party integration plan before any code is written. The timeline also includes App Store and Google Play submission and a buffer for any regulatory review of financial data disclosure requirements that Apple or Google requires for your specific product category.
PCI-DSS controls are designed into the architecture before the first line of code, not added as a checklist at the end. For mobile apps that handle payment card data, we follow the PCI Mobile Payment Acceptance Security Guidelines: card data is never stored on the device; tokenization via Stripe, Adyen, or Braintree is used so raw PAN data never reaches your servers; TLS 1.3 is enforced for all data in transit; and third-party SDKs are assessed for compliance before inclusion. For apps that display card data (balance, partial PAN), we apply strict access controls, session timeout, and screenshot prevention. We provide a compliance architecture document before development starts.
Yes. We build end-to-end KYC onboarding: document capture (passport, driving licence, national ID) with real-time quality validation; liveness detection to prevent photo spoofing; identity verification via Jumio, Onfido, or Stripe Identity; AML and sanctions screening via ComplyAdvantage or similar; and risk scoring routed to a compliance review queue when needed. We design the flow to complete in under 3 minutes for standard users, with exception handling for edge cases. Drop-off at each step is instrumented so you can see exactly where users leave and fix it. The onboarding architecture is documented and approved with your compliance team before build begins.
We connect to Plaid (US, UK, Canada, Europe), TrueLayer (UK, Europe, Australia), MX (US), and Finicity (US). Capabilities covered: read-only account aggregation for balance and transaction history; account verification for ACH and direct debit setup; payment initiation for account-to-account transfers; and income and asset verification for lending decisioning. For markets where open banking aggregators don't operate, we work with direct bank APIs and screen-scraping fallbacks. The integration approach and data scope are confirmed in week-one discovery against your specific use case and target market. Open banking provider selection is consequential: Plaid's coverage differs from TrueLayer's in European markets, and we confirm the right provider for your user geography before the build starts.
React Native and Flutter for iOS and Android from a single codebase - our default for most fintech apps because it halves the testing surface and the compliance review scope. Swift (iOS) and Kotlin (Android) when the product requires deep integration with Apple Pay, Google Pay, or NFC hardware. Backend: Node.js or Python (FastAPI) with PostgreSQL; AWS or GCP for infrastructure with SOC 2-compliant configurations. Payment processing: Stripe, Adyen, or Braintree depending on geography and card scheme requirements. KYC: Onfido, Jumio, or Stripe Identity. Open banking: Plaid, TrueLayer, or MX. The stack is confirmed in the project brief so your compliance and security teams can review vendor dependencies before any build starts.
