I want to bring a simple, intuitive productivity app to life and have it packaged as a ready-to-install APK for the Google Play ecosystem. The concept is aimed at general users, so the flow and visuals should feel instantly familiar to anyone who has ever used a to-do list or note pad on their phone. Scope • Design a clean Material-compliant interface (light and dark themes). • Build the core productivity workflow we finalise together—think along the lines of task lists, calendar hooks, quick notes, or similar essentials. I’ll confirm the exact feature mix before you code, but flexibility to slot in common modules such as reminder notifications or cloud sync will be valuable. • Ensure smooth performance on Android 8.0 and above, with graceful fallback for older devices. Deliverables 1. Signed, install-ready APK (release build). 2. Full Android Studio project with readable, well-commented Kotlin or Java code. 3. Brief setup guide so I can compile future versions myself. Please highlight any prior productivity or utility apps you’ve shipped, relevant libraries you prefer (e.g., Room, WorkManager, Retrofit), and an estimated timeline.
