I’m building a straightforward mobile experience where users earn points every time they tap the screen. The job is Android-only, and the focus is on a clean, lightweight build that tracks taps, stores the running balance safely in the cloud, and syncs it back to the device instantly after each session. Here’s what I need you to hand over: • Registration/login (email or Google) • Main tap interface that increments and displays the balance in real time • Secure, lightweight backend—Firebase is fine, but I’m open to another service if you prefer—to keep balances tamper-proof • Simple admin setting (panel or JSON) so I can adjust the tap-to-point ratio without releasing a new build • Minimal Material-style UI with an ad placeholder ready for AdMob integration • Source code (Android Studio), release-ready APK, and a concise README covering build steps and environment I’ll share my draft wireframes and reward logic as soon as we start. Once these deliverables are met and tested, I plan to push the app live on Google Play within a month. If you can meet that timeline, let’s connect and set up milestones.
