Mobile App Development
React Native and Expo apps with the performance, polish, and native feel your users expect. From prototype to App Store in weeks, not months. Engineers who know the platform deeply enough to tell you exactly where cross-platform ends and native begins.

⚖️
Most teams spend weeks debating native iOS/Android vs React Native before writing a line of code. For the vast majority of business apps, React Native with Expo SDK 52 delivers native-quality UX at a fraction of the timeline and cost. The 5% of use cases that genuinely require full native are real — we'll tell you honestly if you're one of them.

Mobile agencies quote 6 months because they're running multiple projects in parallel, have junior developers learning on your project, and their process has four sign-off stages. We build with Expo, Supabase, and a stack we know deeply. Five fully-specified apps in under 65 hours each. The prototype proves the timeline is achievable.
🎭
Nothing kills user perception of an app faster than janky transitions. React Native's default Animated API runs on the JS thread and can't guarantee 60fps on mid-range devices. Reanimated 3 with worklets runs entirely on the UI thread. The difference is night and day — and it requires engineers who know Reanimated deeply.

Apple's review process is unpredictable. Guideline 4.2 (minimum functionality), 5.1.1 (data collection), and 2.1 (app completeness) are the most common rejection reasons. Getting through App Store review the first time requires specific patterns in your privacy manifest, data use descriptions, and onboarding flows. We've been through it — repeatedly.
How we help
01
Full-stack React Native apps built on Expo SDK 52 with Expo Router for file-based navigation, EAS Build for CI, and OTA updates via Expo Updates. Supabase for auth, database, and storage. Stripe for payments. We move fast because we've built this stack many times — PulseKit (health), Locale (maps), OrderFlow (restaurant), BookSpace (booking), HabitForge (habits) all shipped under 65 hours each.
02
Fluid 60fps animations using Reanimated 3 worklets that execute on the UI thread — completely independent of JavaScript. Gesture Handler for natural touch interactions. Skia for custom graphics. The performance ceiling of React Native is higher than most developers realise — we build to that ceiling.
03
When React Native's built-in APIs aren't enough, we write native modules in Swift/Kotlin. Bluetooth LE, NFC, HealthKit/Health Connect, advanced camera APIs, biometric auth, push notifications via APNs/FCM — we've written the bridge code and understand the platform quirks on both sides.
04
End-to-end App Store and Google Play submission. Privacy manifest configuration, data use description writing, screenshot and metadata optimisation, TestFlight beta management, and the specific patterns that get through Apple review first time. We've handled the edge cases that trip up teams who haven't been through it before.
