I will develop a custom android app using kotlin and firebase
Frank
About this gig
Need a custom Android app built with real Kotlin code and powerful backend logic?
I develop native Android apps using Kotlin, no templates, no drag-and-drop gimmicks. You'll get clean, fast, and scalable apps that are built to last.
I specialize in:
- Custom UI using Material Design
- Firebase integration (auth, database, analytics)
- App logic & screen navigation
- Google Play Services (achievements, leaderboards)
- AdMob & in-app purchases (on request)
Every app is built from scratch, based on your needs. Whether you're launching a prototype, a tool, or a production-ready app I'll deliver rock-solid code and professional structure.
Starter package: Ideal for simple concepts or UI prototypes
Core package: Multi-screen MVP with Firebase
Premium package: Full-featured app with backend, polish, and source code
You also have options to include source code, request extra revisions, or add Play Store submission.
Lets build something that works and works damn well.

FAQ
Do I get the source code?
Only included in the Premium package. If you're on Starter or Core and need the source, you can add it as a gig extra.
Can you publish the app to the Play Store for me?
Yes. I offer Play Store submission as a gig extra. You’ll need to provide access to your developer account and the required listing info.
Can you integrate Firebase into my app?
Yes — Firebase features like authentication, realtime database, analytics, and remote config are included in the Core and Premium packages. You can also request it as an extra for the Starter package.
What tools do you use?
I use Android Studio, Kotlin, Firebase, and Google Play Services — all native and professional tools. No no-code platforms, no shortcuts.
Can I request changes after delivery?
Each package includes a set number of revisions. If you need more, just add the “Additional Revision” extra to your order.
Can you fix code from another developer?
I can take a look, but I don’t patch bad code for cheap. Message me first and we’ll talk real solutions.
