I kept making workout plans for myself and for friends. Same exercises, different variations, trying to keep it fresh. It was taking more time than the actual training.

I built a self-monitoring calisthenics app focused on high reps. You open it, hit generate, and it handles everything: exercise selection, rep targets, rest timing.

It tests your max reps first (your baseline), then multiplies that to set your total target for the session. The randomisation keeps every workout different without any planning on your end.It also has two training modes. Circuit rotates between exercises as you go. Comp mode is inspired by Calisthenics Cup multiple exercise cards done sequentially, no moving on until the current exercise is complete.

Built as a single HTML file through conversation with Claude. No backend, no framework, runs straight from your phone.
