I will do mobile app development for android and ios app
Kausar
About this gig
One codebase. Two app stores. Your idea, working on Android and iOS.
I build mobile apps end to end. Depending on what your project actually needs, I use Flutter, React Native, or fully native Kotlin and Swift, so you get the right tool for the job.
WHAT YOU GET
- A real, working app for Android and iOS
- Clean custom UI built from your idea, Figma file or sketch
- App icon and splash screen
- API and backend integration, Firebase or Supabase
- Login, push notifications, payments and offline support
- Full source code, yours to keep
HOW IT WORKS
1. You tell me what the app should do
2. I send a screen list and plan before writing any code
3. You get test builds you can install on your own phone
4. I hand over the source code, and submit to the stores if you want
WHY ME
3+ years building production software full time. Clean, documented, structured code that any developer can pick up later. No disappearing mid project.
Not sure which technology fits your idea? Message me first. I will tell you honestly which one makes sense for your budget and timeline, even if the answer is that you do not need an app at all.

FAQ
Do I get one app or two?
One project, two apps. React Native builds a real Android app and a real iOS app from the same codebase, so you pay once instead of twice.
Do I get the source code?
Yes, always. Full source code is included in every package. You own it and you are never locked to me.
Can you publish it to Google Play and the App Store?
Yes, store submission is included in the Full App package. You will need your own developer accounts, and I will guide you through creating them.
I only have an idea, no design. Is that a problem?
Not at all. I design the screens for you. If you already have a Figma file or even rough sketches, that speeds things up and keeps the look exactly as you want.
Will the app work offline or need a backend?
Both are possible. I can build a fully offline app, or connect it to a backend with Firebase, Supabase or your own API. Tell me what the app needs to do.
What if my idea is bigger than these packages?
Then I will tell you before you order, and send a custom offer with a realistic price and timeline. I would rather scope it honestly than deliver half an app.
Do you use Flutter or React Native?
Whichever fits your project. Flutter for heavy custom UI and smooth animation, React Native if you already have a JavaScript or React codebase, and fully native Kotlin or Swift for platform heavy apps. I will recommend one before you order.
