MVP development
A working first version with only the essential features, so you reach the market fast and test the idea without overspending on speculation.
React Native
React Native Apps from One Shared Codebase
iOS and Android without two codebases, two release cycles, and two teams. We build React Native products with shared logic at the core and native support exactly where the app needs it.

React Native
React Native work built around real product decisions
React Native pays off when shared code, native modules, and release planning are settled before the first sprint. That is where we start.
Full application builds
Production apps for both stores in clean, organized code your own team can take over later, fitted to your business goals and device landscape.
Native module integration
Biometrics, GPS, Bluetooth, and other heavy device features get custom Swift and Kotlin modules, so you keep native capability without slowdown.
Migration to one codebase
We merge separate iOS and Android apps into one shared codebase in safe increments, so you never delete a live app or start from scratch.
Cross-platform UI and UX
Screens designed to feel natural on both iPhone and Android, because a familiar layout is what keeps users from deleting the app.
Support and maintenance
After launch we handle OS updates, crash fixes, and store compliance, so you do not need to hire full-time mobile staff to keep the app alive.
Want one build that ships to both stores?
Send the requirements and we will map the shared architecture, native module needs, and release path with a fixed USD scope.

The path to a smooth launch
- 01
Scope and platform fit
Users, core flows, and feature set are defined first. This is also where we confirm React Native is genuinely the right choice.
- 02
Architecture planning
Navigation, state management, API structure, local storage, and native module needs are planned before development begins.
- 03
Shared UI design
Screens, reusable components, and platform-specific behavior are mapped so the app feels right on both iOS and Android.
- 04
Sprint development
Built in sprints with regular demos, both platforms taking shape together from one shared codebase.
- 05
Real device QA
Physical iPhones, Android handsets, and tablets: layout distortion, crashes, memory leaks, battery use, and OS-specific behavior.
- 06
Store launch and support
App Store and Google Play submissions prepared and managed, with updates and compatibility work continuing after launch.
Why AIoptimix
The standards that keep your app fast
One product, two stores
One codebase powers both platforms, so features, fixes, and updates ship once instead of being duplicated across two roadmaps.
Over-the-air fixes
For JavaScript, styling, and asset changes we configure over-the-air releases where store rules allow, so small fixes reach users in minutes, not review queues.
Hardware-verified quality
We test on physical devices across brands and generations to catch the layout, battery, and crash issues that simulators reliably miss.
Aligned to your timezone
Working hours are agreed to overlap with your team, so questions get answered in your day, not in an overnight email loop.

Frequently asked questions.
What is React Native development?
React Native is an open-source framework for building real mobile apps in JavaScript and TypeScript. Unlike web-view wrappers, it renders through the native iOS and Android engines, so users get native look, smooth animation, and fast touch response from one shared codebase.
How much code is shared between iOS and Android?
The large majority of it. Core logic, data handling, and most interface code live in one repository, so features and fixes are written once and released to both stores together. Only genuinely platform-specific behavior needs separate code.
Will performance match a native app?
For typical business products, yes. The modern React Native architecture communicates directly with device hardware, keeping interaction fluid. Intensive 3D, heavy video editing, and complex multi-threading are the exceptions, and we will steer you native if your product is one.
Can you migrate an existing native app to React Native?
Yes, incrementally. New cross-platform views and modules are placed inside your active native app step by step, so new features build from one shared pipeline while your proven legacy code keeps running underneath. No rewrite, no relaunch.
How do over-the-air updates work?
Where the app and store policies allow it, JavaScript, styling, and asset updates can be delivered straight to user devices without waiting on store review. The app fetches the change silently in the background, which turns small hotfixes from a review queue into a minutes-long deploy.
