Built by a sports physiotherapist. Evidence-based rest timers with guided breathing between sets. Apple Watch, Live Activity, lock screen. No ads, no subscriptions. Calmset gives you one thing and does it well: precise rest timing between sets, based on exercise science. Rest periods matter. Too short and you leave strength on the table.

Apple Watch got a big rework. iPhone's more stable too. Apple Watch • The timer runs on the Watch itself now. No more waiting for the iPhone to catch up. • Wrist down and rest ends? Your Watch taps you on time. • Digital Crown picker for custom durations, right on the Watch. • Delete saved presets from the Watch too. • Pro actually reaches the Watch now. iPhone • Buying Pro is solid again. • Dynamic Island and Live Activity keep the timer visible with the phone locked or in another app. • Quieter home screen between workouts. • Home's mode row is cleaner. Just the four scientific presets now. A lot of this came from folks telling us what was rough. Thanks.
