Could you build this?
Partial The UI and backend are simple, but creating a reliable Android app that intercepts native phone calls, verifies 60-second talk duration, and enforces strict app-blocking requires deep Android OS permission handling.
What it would actually take: The app needs a native Android implementation (Kotlin) leveraging Accessibility Services, `UsageStatsManager`, `TelecomManager`/CallScreeningService, and overlay permissions to monitor active call durations accurately. The challenging component is ensuring the background service survives aggressive OS battery optimization across various Android OEMs (Xiaomi, Samsung) without leaking call audio or violating Google Play policy restrictions on call logs and accessibility. This requires specialized native Android systems engineering experience.
