Build your own workout tracker from one prompt. No account needed
Describe your tracker, get a working app with sets, reps and a rest timer.
What you get
A working workout tracker app opens in the preview pane beside the chat.
You log the exercise, the sets, the reps and the weight. It shows what you lifted last session, and it has a rest timer.
The prompt and the result
This is the prompt the guest chat sends, and the screen under it is the app it built.

What this isn't
It is not a standalone workout app: the tracker lives in the chat it was built in, it publishes no address of its own, and it syncs with no account or wearable.
