Android Free Fire Tournament App

I need an Android-only application that lets gamers join my Free Fire tournaments quickly and securely. The single must-have feature right now is a streamlined player-registration flow that relies on phone-number verification rather than email or social logins, so every user who downloads the app can sign up with an OTP and land straight inside the lobby.

Once registered, participants should see their profile and a simple “Join Tournament” button (backend logic can be stubbed for now; I mainly want the registration piece working flawlessly). An intuitive material-design interface, clean Firebase or similar real-time database integration for storing user details, and well-commented source code are all part of the hand-off.

Deliverables
• Production-ready APK and full source code
• Brief setup document outlining dependencies, build steps, and how to swap SMS gateway credentials
• One round of bug-fix support after first test build

If you’ve built gaming or event signup apps before, that’s a plus. I’m aiming for a lightweight, fast first release, with the option to expand into live leaderboards and match scheduling after this milestone goes smoothly.
