I need a lightweight Android APK that lets my field team log and review outlet-level sales activity. The core purpose is to capture two key data points for every outlet they visit: • Daily sales volume • Current inventory levels Beyond that, the app should store each record locally (SQLite is fine) and allow a quick export to CSV or JSON so I can pull the data into my existing dashboards. At this stage I’m not asking for user authentication, push notifications, or in-app purchases—just the smoothest possible workflow for entering, editing, and exporting the numbers. Deliverables I expect • Production-ready APK plus full Android Studio source • Clear, commented code so my in-house team can extend it later • A brief README covering build steps and the data schema Once the basic tracker is solid, I may commission follow-up work to add sync, GPS tagging, or authentication, so clean architecture now is important. If you’ve built similar data-capture apps before, I’d love to see them.
