AppMama

Apps made on a phone

Each one: a single message, built and installed on the same phone · Claude · Samsung Galaxy F62 (2021)

Every app below started as one message typed into AppMama on an ordinary mid-range Android phone. The AI wrote the code, the phone built it, and Android installed it — no computer anywhere. The times are from the screen recordings: prompt sent to app ready, for the first build of a brand-new app. Copy any prompt and make your own version.
