Onset

Most workout apps die in week two because logging is a chore: too many taps between finishing a set and getting back to lifting. Onset optimizes exactly one moment, the thirty seconds between sets, and everything else follows from the data that falls out of it.

Log a set in a couple of taps and the app quietly builds the interesting stuff on its own: weekly volume, personal records, and estimated one‑rep‑max trends per lift, so you can watch strength move week over week without ever filling in a spreadsheet.

I designed and built it end to end with Claude Code, and it's been my daily gym companion since. This one isn't a client project. It's the app I wanted to exist.
