Kronset
Free interval timer
Set it up, press start.
Kronset counts the rest.
A simple interval timer for HIIT, Tabata, running intervals and circuits. Sounds tell you when to go and when to stop, so you never have to look at the screen.
Build any workout
Work, rest, long rest and repeat steps. Repeats can be nested, and the pointless last rest is skipped for you. Or start with Tabata 20/10, Pyramid 8·6·4 or 30/30 Run.
Readable from afar
A big timer, different colours for work and rest, and the next step always on screen.
Sounds that guide you
A countdown beep in the last three seconds and seven tones to choose from. Works in silent mode and plays over your music.
No account, no tracking
Free, with no ads, no analytics and no internet. Your workouts stay on your phone. In 11 languages.

FAQ
Do cues keep playing when I lock the screen? Yes. The screen stays on during a workout, and if you lock the phone yourself, the timer and its cues keep going.
How do I edit a workout? Press and hold its tile on the home screen and choose Edit.
How do I change the language? Kronset follows your phone's language. To pick another one, open Settings and choose Language.
