Mobile App Development
Mobile apps that perform on real devices
We build React Native apps for AI products that need to perform on real devices: iOS and Android from one senior team, with native modules where they are the honest engineering choice.
Why choose us for mobile app development?
A mobile app is judged on a real device, on a weak signal, after a store reviewer has had their say, and that is the standard the work is held to.
One production codebase
React Native and TypeScript deliver iOS and Android from one codebase, with native Swift or Kotlin modules where the product genuinely needs them, so behaviour stays aligned across both platforms.
AI that respects mobile constraints
Streaming responses, camera and voice inputs, model fallbacks, secure API access and on-device inference where latency or privacy demands it are designed in, because AI on a phone behaves differently from AI in a browser.
Device + wearable integrations
HealthKit, Health Connect, Bluetooth devices, camera, location, biometrics, notifications and background tasks are engineered against real hardware, which is where they fail when only a simulator has seen them.
Offline and unreliable-network support
Local persistence, queued writes, conflict resolution, retry policy and visible sync states are an architecture decision taken up front, for products that cannot assume perfect connectivity.
Payments + subscriptions
Apple Pay, Google Pay, Stripe, StoreKit, Google Play Billing, entitlement handling and receipt validation are built once and properly, so payment logic is never the brittle part of the app.
Store-ready release pipeline
Signing, TestFlight, internal tracks, staged rollout, crash reporting and review preparation are set up in your accounts, with the release runbooks your team keeps.
What we build in mobile app development
Apps where the phone is doing real work: sensors, payments, offline data and AI features that have to hold up on the device in hand.
Consumer apps
Apps for the public, with the performance that keeps a first-time user.
- Onboarding that reaches value before the first signup wall
- Push notifications people choose to keep on
- Store listings, reviews and crash-free releases
Field-service apps
Apps for people working away from a desk, on site and on the road.
- Offline capture with sync queued for signal
- Location, photos and signatures on every job
- Back-office view of work as it happens
Marketplace apps
Two-sided apps with the moderation tools both sides rely on.
- Listings, search and matching between both sides
- In-app messaging with reporting and blocking
- Payments split into fees and payouts
Fintech and payments
Apps that move money, with the handling the app stores require.
- Apple Pay, Google Pay and Stripe checkout
- Subscriptions, entitlements and receipts kept in sync
- Biometric login and secure storage for credentials
Health and fitness
Apps reading from health platforms and wearables, engineered against real hardware.
- HealthKit and Health Connect permissions handled per platform
- Bluetooth wearables paired, synced and reconnected
- Sensitive data stored and shared with consent
Companion apps for SaaS
The mobile face of a web product, sharing its backend and auth.
- Same account and permissions on every screen
- The workflows people need away from their desk
- Push and deep links back into the web product

How we build mobile app development
Four stages, from the devices and integrations in scope to a staged rollout and 30 days of launch support.
Scope devices and integrations
We define OS support, device permissions, backend contracts, AI behaviour, offline requirements, analytics, and store constraints before design locks.
Design native-feeling flows
Accessible iOS and Android interaction patterns, navigation, loading and error states, and prototypes tested on representative screen sizes.
Build and test on hardware
Two-week delivery increments, automated tests, device-matrix QA, performance profiling, and beta builds your stakeholders can use throughout.
Release and observe
TestFlight and Play testing tracks, store submission, staged production rollout, crash monitoring, analytics validation, and 30 days of launch support.

Mobile development questions
Direct answers about React Native, native code, store submission, ownership, and delivery cost.
For most product apps, a shared TypeScript codebase gives materially faster delivery and keeps iOS and Android behaviour aligned. We do not pretend every problem belongs in JavaScript: native modules are the right answer for some device APIs and performance-critical paths.
