What it still needs
This is a working interface, not a finished product — and here is the honest gap, in the generator’s own words. Signing up is what closes it: the agent writes the backend, you approve each change as a diff, and the code is yours to export.
- Database and schema — defining relationships between roommates, flat groups, and expense line items for persistent storage.
- User accounts and login — allowing roommates to join a specific "Flat" via invite codes and secure their individual profiles.
- Settlement tracking — adding a "Settle Up" feature to record when one roommate pays another back via cash or external apps.
- Recurring expenses — automating monthly entries for fixed costs like rent, internet, and utility subscriptions.
- Image uploads — implementing a way to attach photos of receipts to specific expense entries for verification.
