Mobile Development
Native-feeling iOS and Android apps built with React Native and Expo — offline-ready, store-approved, and performant on mid-range devices.
The Problem We Solve
Most mobile apps fail on launch day for one of two reasons: the build is fragile, or the build is slow. Users uninstall within a week, reviews tank, and the team spends the next six months firefighting instead of shipping features.
The fragile path looks like this: inconsistent behavior across iOS and Android, random crashes that only reproduce on specific OS versions, broken deep links, no offline support, and store review rejections eating two weeks per release. Every fix creates two new regressions.
The slow path is quieter but just as damaging: laggy scrolling on mid-range Android, 8-second cold starts, jank during animations, and a battery drain bad enough that users notice. Even a feature-rich app loses if it feels heavy.
On top of that, most teams underestimate mobile operations. Over-the-air updates aren't wired in, crash reports are noise, analytics are instrumented wrong, and nobody's testing on real devices — just simulators. By the time you spot a regression in production, it's already in 40% of users.
Our Approach
We default to React Native with Expo because it lets us ship to iOS and Android from one codebase without sacrificing native feel — and because OTA updates via EAS let us patch JS-layer bugs in hours, not weeks.
Performance is designed in, not bolted on. We virtualize long lists, profile on mid-tier Android throughout development, keep the JS bundle small, move heavy work off the UI thread, and use native-driven animations for 60fps interactions. Mid-range devices are our performance target, not flagships.
Offline is a first-class feature. Core flows work without connectivity using local storage and background sync. Conflict resolution is handled server-side with a clear data model, not patched reactively once users complain.
We treat the stores as a shipping target. TestFlight and internal Play tracks from week one, store listings drafted early, privacy manifests prepared before review, and launch-readiness QA on a device matrix that matches your user base.
Observability ships with the app. Sentry for crashes, analytics via Firebase/Mixpanel/PostHog instrumented around the events that matter, and feature flags for safe rollouts. Regressions get caught in the first 5% of users — not the first 50%.
What You'll Receive
Every deliverable, reviewed and ready to ship.
iOS + Android apps
Shared React Native codebase with platform-specific polish where it matters.
Backend integration layer
Typed API clients, auth, offline cache, and sync — connected to your existing backend or one we build.
Push notifications
Firebase Cloud Messaging or OneSignal, wired to your backend with segmented targeting.
Store submissions
App Store + Play Store listings, screenshots, privacy declarations, and TestFlight / internal tracks configured.
Analytics + crash reporting
Sentry, Firebase/Mixpanel events instrumented around the flows that move the business.
OTA update pipeline
Expo EAS Update configured so JS-layer fixes ship in hours, not store-review cycles.
Post-launch support
First 30 days of bug fixes, store-review response, and performance tuning included.
How We Work
A transparent process, every step of the way.
- 1
Discovery + technical architecture
User flows, store requirements, backend contracts, and a realistic launch scope for MVP vs v1.
- 2
Design + prototyping
Mobile-native patterns, gesture handling, and clickable prototypes validated before engineering starts.
- 3
Engineering sprints
Two-week sprints, TestFlight / Play internal builds weekly, demos every Friday with real-device QA.
- 4
Store submission & review
Store listings, privacy manifests, and submission. We respond to review feedback until both stores approve.
- 5
Launch + tuning
Phased rollout, crash monitoring, performance tuning on mid-range devices, and a monthly retainer option for ongoing work.

Frequently Asked Questions
Both. We default to React Native / Expo for projects where iOS and Android share most features — it cuts cost and time by roughly 40%. For apps with heavy native requirements, we build native Swift or Kotlin.
