Mobile App Development

Native where performance or platform APIs demand it, cross-platform where shared code saves real budget without costing users a native feel — decided per project, not by default.

React NativeSwiftKotlinGraphQLFirebase

The native-versus-cross-platform question has no default answer. If your app depends on biometrics, background processing, or heavy platform APIs, we build native in Swift and Kotlin. If shared code saves real budget without costing a native feel, we use React Native. We decide per project, against your constraints.

Mobile has failure modes web does not: flaky connectivity, app-store review, and users who never update. We design an offline-first data layer where connectivity cannot be assumed, and plan for staged rollouts and forced-upgrade paths from the start.

We handle App Store and Play Store submission, including rejection triage, and wire crash reporting and release monitoring before launch, so the first bad build is caught by you and not by a one-star review.

What changes in the codebase

balance.ts

 export async function getBalance(userId: string) {
−  const res = await fetch(`/api/legacy/balance/${userId}`);
−  return res.json(); // no retry, no timeout, no typed shape
+  const res = await client.balances.get(userId, {
+    retry: 3, timeoutMs: 2000,
+  });
+  return BalanceSchema.parse(res);
 }

Native suits performance-critical or platform-heavy apps. React Native suits products where one team and one codebase matter more. We recommend one after reviewing your feature list and roadmap.

Yes, including metadata, privacy declarations, and review-rejection fixes.

Yes. We commonly reuse your existing API layer and redesign the flows that behave differently on mobile, such as onboarding and authentication.
