I need two lightweight Android apps to streamline daily operations in my small dairy. Milk Collection app • For our dairy managers to log each pickup in seconds. • Must track quantity and quality remarks, then calculate and display what we owe each farmer. • Basic payment-history screen and a quick CSV or PDF export are all I need at this stage. Dairy Management app • Should maintain real-time inventory levels and automatically update stock whenever milk is processed or packaged. • Track sales so I can review daily revenue and simple trend charts. • A single-tap export to CSV keeps bookkeeping easy. Both apps should: • Work offline and sync to a lightweight cloud option (Firebase or Google Sheets) once a connection returns. • Run smoothly on standard Android phones (Android 8.0+). • Come with clean, intuitive screens—no advanced UI polish required right now. Deliverables • Signed APKs ready for on-farm testing • Complete Android Studio source code • One-page setup and usage guide I’m after a quick, functional prototype I can test within two weeks. If you already have reusable modules that cover collection tracking, farmer payment processing, inventory management, and sales tracking, feel free to adapt them.
