The challenge
Grocery shopping spreads across stores, budgets, and household members, and a plain checklist does not track spending or stay in sync when two people shop.
What we built
CartFlow organizes trips by store, captures item details like quantity, price, and photos, and tracks estimated spend against a budget as you move through the aisles. Lists share by link or email, work offline, and sync back when the connection returns.
- Cross-platform Expo app
- Offline-first data layer
- Subscription tier
- App Store release
Outcome
CartFlow came from wanting a grocery list that actually understood budgets and shared cleanly with a partner, instead of a notes file that fell out of date.
