Clinch showing round 1 of 12 with a 3:00 countdown

Built for the gym floor

Bells on a locked phone

Clinch keeps running through your workout, so round, warning and finish bells ring with the screen off.

Your workout on the Lock Screen

Total time, a countdown block for each round and rest, and when you'll finish. Pause or skip right on the card, no unlocking.

Calls the rounds

Hear “Round 3”, “Final round” and “10 seconds” so you never have to look at your phone.

Skip or take more rest

Skip to the next round or add 30 seconds of rest, and the rest of the workout moves to match.

Boxing and intervals

Rounds, rest and warning time, plus HIIT, Tabata and EMOM presets.

Plays over your music

Keep Spotify, Apple Music or any app playing. Your music dips under each bell and call.

Clock-only landscape

Turn the phone sideways and it's just the clock, big enough to read from the bag.

Private by design

Everything stays on your device. No sign-up, no ads, no analytics.
