100 Apps in 100 Days

One mobile app a day, on your own phone, built with an AI agent. Days are grouped in tens; every tenth day is a Kit day, when everything you built gets folded back into the starting point for the next ten.

You check every step on your own phone. Same flow as the other tracks.
