React Native App Development

Cross-platform mobile apps built once in React Native and shipped to iOS and Android, without the performance compromises that give cross-platform a bad name.

React Native done well ships genuinely native-feeling apps to both platforms from one codebase. React Native done poorly, unoptimized lists, bridge-heavy native module usage, no attention to platform-specific behavior, ships something that visibly feels like a cross-platform compromise. The difference is almost entirely in execution, not the framework itself.

01

A previous React Native app feels sluggish compared to native

Scroll performance, animation jank, or slow screen transitions make the app feel like a compromise instead of a real product. This is almost always fixable, but it needs someone who understands where React Native performance actually breaks down.

02

Choosing between React Native, Flutter, and fully native is unclear

Every option has trade-offs that get glossed over in generic comparisons. The right call depends on your team, timeline, and how platform-specific the app needs to be, not a one-size-fits-all recommendation.

03

One codebase but the iOS and Android experience diverges anyway

Platform-specific quirks (navigation patterns, permissions, push notification behavior) got handled inconsistently, so users on one platform get a worse experience than the other.

Scope

What you get.

A single codebase, genuinely shared across platforms

Business logic and most UI shared, with platform-specific handling only where it actually matters (navigation conventions, permissions, native modules).

Performance treated as a first-class requirement

List rendering, animations, and navigation profiled and optimized, not left to whatever the default gives you.

Native module integration where it is genuinely needed

Camera, biometrics, push notifications, and other native capabilities wired in cleanly, without over-reaching into unnecessary native code.

App store submission handled end to end

iOS App Store and Google Play submission, including the review-process gotchas that catch first-time submitters off guard.

A build that is actually maintainable after launch

Clean component structure and state management so your team (or ours, on retainer) can keep shipping features without fighting the codebase.

How it works

Four steps, no mystery.

01

Quick scoping call

A short call (or async over WhatsApp) to understand what you're working with and what "done" actually looks like for you.

02

Fixed scope, no surprises

A clear written plan of what's included and how long it takes, before any work starts.

03

The actual work

Progress you can see, not a black box. You get updates as milestones land, not just a status report at the end.

04

Handover

Everything documented and handed over cleanly, with a walkthrough so your team isn't stuck waiting on me for routine changes.

Questions

Frequently asked.

Depends on your team's existing skills, how platform-specific the app needs to be, and timeline. We give an honest recommendation based on your actual constraints, not a default answer.
