Relic Trove Collector Grid

Relic Trove Collector Grid is a personal collection manager built for stamp and coin enthusiasts who want a clean, visual way to keep track of every piece they own.

The app presents your collection as a thumbnail grid of large, browsable cards — each one representing a category or era you define. Tap any card to dive into its contents, add detailed notes, apply custom tags, and sort or filter items by date, name, or priority.

Everything runs locally on your device. No account required, no internet connection needed, no data ever leaves your phone.

- Multiple view modes: compact rows, cards, or grid
