I will do secure mobile app development, react native ios and android app


About this gig
Secure mobile app development for iOS and Android, built with React Native and Expo, so you get one clean codebase, a fast and smooth app, and an interface your users understand in seconds.
I build apps security first. Every package and config file is checked for hidden code before it runs, logins live in the phone's secure storage, and your secret keys never sit inside the app.
What I can build into your app:
- Email, Google and Apple login
- Stripe payments and in-app subscriptions
- Push notifications, maps, camera and real-time chat
- API and backend connection
- App Store and Google Play publishing (TestFlight included)
Why work with me:
- Easy, clean UI with smooth animations
- Fast loading, tested on iOS and Android
- Full source code; you own everything
Send me your idea, even a rough note, and I will reply with a plan, a screen list and an honest timeline before you order.

FAQ
Which platforms do you build the mobile app for?
Both iOS and Android. I use React Native with Expo, so one codebase runs on iPhone and Android phones. That keeps your mobile app development cost lower, updates faster, and the look and feel the same on both platforms.
How do you keep my mobile app secure?
Security is the core of this gig. Every package and config file gets a hidden-code check before it runs. Login tokens live in the phone's secure storage, secret keys stay on the server (never inside the app), all traffic uses HTTPS, and the app asks only for the permissions it needs.
Can you publish my app to the App Store and Google Play?
Yes. The Standard and Premium packages include App Store and Google Play publishing, plus TestFlight testing before launch. You will need your own Apple Developer and Google Play Console accounts, so the app is published under your name and you keep full control.
I only have an app idea. Can you still build it?
Yes. Send me the idea in plain words. I will turn it into a screen list and a simple plan, suggest what belongs in the first version (MVP), and give you an honest timeline before you place the order.
Can you fix or check an existing app built by another developer?
Yes. I can review existing React Native or Expo app code, check it for hidden or unsafe code, fix bugs and finish the build. Send me a message first so I can look at the project and send you a custom offer.
Will I own the source code of my mobile app?
Yes, 100%. You get the full source code, and every account (App Store, Google Play, backend, payment) stays in your name.
