The product

Construction and inspection teams need photographic proof of where and when work happened. GeoStamp stamps every photo with location, address and timestamp, organises them into per-project photo logs, and exports client-ready PDF site reports in one tap.

Built as a complete product, not a demo: monetisation with entitlements and a paywall, remote config, offline-first SQLite storage, and a prepared store kit — listing copy, ASO keywords and a data-safety document.
