I’m looking for an experienced Android developer to build a lightweight anti-theft alarm application. The goal of the app is to trigger a loud alarm if someone moves or disconnects the phone without authorization. Core Features • Motion detection using accelerometer • Alarm if charger unplugged • Loud siren alarm even in silent mode • PIN code to stop alarm • Background service (cannot be easily closed) • Simple UI: Arm / Disarm button • Optional vibration + flash alert Additional Features (Nice to Have) • Sensitivity adjustment • Email alert when alarm triggers • Auto start after reboot Technical Requirements • Android (Kotlin preferred) • Support Android 10+ • Clean code and comments • Source code included Deliverables • Android Studio project • APK for testing • Documentation
