Mujhe ek simple offline Android app banana hai — naam "Bonus for Punctual". App me 5 buttons honge (number 1 to 5). Har labour ka ek fixed number hai. Jab labour apne number wale button par tap karega: - Uska arrival time record ho jayega. - Agar wo scheduled time (7:05 AM) se pehle aaya hai to uske early minutes × ₹2.5 ka bonus turant screen par show ho. - Button ek din ke liye disable ho jaye (next day reset ho jaye). - Data phone memory (local storage) me save ho, bina internet ke. Deliverables: 1. Working APK file (offline) 2. Source code (Cordova / Android Studio) 3. Small guide - kaise install & build karna hai 4. 1 week support for bug
