00:37 play online

important notes:
- the app doesn't contain any exercises or routines. add and do exercises you know how to do properly. 00:37 does not replace a mentor or classes.
- the app is a side project, mostly designed for personal use, made available for free. I may update it occasionally, but don't expect regular updates or convenient features. I may also remove features that don't work for me or change things in ways you may not like; that's part of the deal here.

features:
- 5 types of exercises display time, repetitions, or amounts in different ways.
- add a metronome, setup time, reminder sounds, tags, and notes to your exercises.
- create sets and routines of exercises.
- save your sessions so you can see how you progress.
