Repcrumb

Repcrumb turns fitness into a small, satisfying loop: one crumb equals one quick set. Instead of asking someone to start a full workout, the app gives them the next tiny action they can do with the gear they actually have around them.

The product centers on a gear inventory system. Users select their tiny gym — bodyweight, floor space, chair, doorway, resistance bands, dumbbells, pull-up bar, outdoor space, and more — and Repcrumb unlocks matching movement crumbs. Locked moves stay visible as previews, so adding gear feels more like a game loadout than a settings form.

The app is built as a Nuxt 4 PWA with Supabase auth for account sign-in, local-first workout logging, a daily target loop, streaks, records, and a calendar that makes consistency visible. The goal is to make movement feel approachable: open the app, do one quick thing, get credit, repeat.
