Tandem

Splitting money with someone you live with should feel easy, and it felt like accounting homework. People dreaded opening the app, and plenty of couples were quietly keeping their own spreadsheets on the side.

Reframed the whole thing around the shared view instead of the ledger. A calm home screen, one clear number for where you stand, and a way to settle up that takes two taps and zero math.

The real signal was the mood change. People went from avoiding the app to checking it together over coffee, and a few started nudging friends toward it without being asked. More trials turn into paying accounts now, and the folks who join tend to stick around past those wobbly first few months.
