I want to replace manual spreadsheets with a straightforward mobile solution focused on data entry. The app’s sole purpose is data collection, so the interface should open directly to a clean form where users can type values, scan barcodes, attach photos, and tag GPS coordinates if available. Core requirements • Runs smoothly on Android; an iOS build is a welcome bonus. • Customisable form fields that I can add, reorder, or hide without editing code. • Offline capture with automatic sync to a lightweight cloud database (Google Sheets, Firebase, or another simple option you propose). • Export options to CSV or Excel so I can review the raw data anytime. • Basic user authentication—email + password is enough—to keep entries separated by user. Deliverables 1. Compiled app file(s) ready to install. 2. Full source code and build instructions. 3. A short walkthrough showing how to modify form fields and retrieve exported data. Keep the design minimal; performance and ease of use matter more than fancy graphics. If you have experience in data-entry automation or field-survey apps, showcase a quick example in your proposal so I can gauge fit.
