React Native App: iOS & Android

Cross-platform iOS and Android. Includes Bridge Optimization, Custom Native Modules, Hermes Engine Integration and OTA Updates (CodePush) — delivered by…

React Native builds iOS and Android apps from one JavaScript codebase while still using native platform capabilities. IQDigital develops React Native apps with an optimised bridge for smooth interfaces, the Hermes engine for faster start-up, custom native modules for hardware such as Bluetooth or biometrics, and over-the-air updates for quick fixes.

Who it's for

  • Companies that need an iOS and an Android app without two engineering teams
  • Product teams that ship frequent updates and fixes
  • Apps that need hardware access such as Bluetooth, sensors or biometrics

What is React Native?

The dilemma of 'Native vs. Cross-Platform' is solved. IQDigital leverages React Native to deliver indistinguishable-from-native experiences on both iOS and Android from a single codebase. We reject the notion that cross-platform means compromise. By bridging JavaScript with native platform APIs, we build apps that possess the smooth 60fps performance of Swift or Kotlin, with the development velocity of the web.

How we keep the app fast

Our approach goes deep into the 'Native Bridge.' We optimize the communication between the JavaScript thread and the Native thread to prevent UI blocking, ensuring buttery smooth animations and gestures. We utilize the Hermes engine to drastically reduce app start-up time and APK size. We do not rely solely on third-party libraries; we write custom native modules when specific hardware access (Bluetooth, Gyroscope, Biometrics) is required.

How over-the-air updates work

We architect for 'Over-the-Air' (OTA) updates using CodePush, allowing you to ship hotfixes and feature updates instantly without waiting for App Store review cycles. This agility is a game-changer for growth-focused companies. From complex fintech dashboards to media-rich social apps, we build mobile solutions that scale to millions of users without the overhead of maintaining two separate engineering teams.

What's included

  • Bridge Optimization — Ensuring 60fps performance on main thread.
  • Custom Native Modules — Direct access to hardware APIs when needed.
  • Hermes Engine Integration — Optimized start-up times and memory usage.
  • OTA Updates (CodePush) — Bypassing app store delays for critical fixes.

How an engagement runs

  1. Diagnose (Week 1) — We find the money before we spend yours.
  2. Build (2–8 weeks) — Senior engineers. Your stack. Weekly proof.
  3. Launch (Go-live) — Released against a baseline, not a hope.
  4. Compound (Ongoing) — The second month should beat the first.

How the work is scoped

  • Engagement: Fixed-scope project

Questions about React Native App

Is a React Native app as good as a native app?

For most products, yes. React Native renders real native components and can call native APIs directly. We tune the communication between the JavaScript and native threads so animations and gestures stay smooth.

Can React Native use device hardware?

Yes. Where libraries fall short, we write custom native modules for hardware such as Bluetooth, the gyroscope or biometric authentication.

What is the Hermes engine?

A JavaScript engine built for React Native that reduces app start-up time, memory use and app size.

Can we update the app without waiting for App Store review?

For JavaScript changes, yes: over-the-air (OTA) updates, for example with CodePush, ship hotfixes and feature updates directly. Changes to native code still go through the stores.
