I run a growing business and still rely on spreadsheets to keep tabs on every item on my shelves. I now need a dedicated Android app that lets me record products, update quantities, and view current stock without the complexity of order or supplier modules. Core requirements • Android-only build, compatible with recent OS versions. • Simple, intuitive interface to add, edit, and archive items. • Manual or batch quantity adjustments (barcode scan or quick-type—open to your suggestion). • Search and filter to locate products fast. • Export current stock to CSV for backup or reporting. • No real-time syncing is required; local storage with manual refresh or scheduled updates is enough. Deliverables 1. Signed APK ready for installation. 2. Full source code and clear build instructions. 3. Brief user guide that shows the main flows: add item, adjust stock, export list. I value clean code, straightforward UI/UX, and clear communication during development. If you have examples of similar lightweight stock apps, please include them when you respond.
