Restbell: Sets, Rounds & Rest
Time your rest between sets
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
The timer that never charges you to press start. Rest between sets, rounds inside intervals — on your phone and on your wrist.
The timer that never charges you to press start.
Restbell times the two gaps in a training session — the rest between your lifting sets, and the work and rest blocks of interval training. One object does both, so a push day and a Tabata session live in the same app instead of two.
QUICK REST
Finish a set, one tap. The countdown runs with sound and haptics while your phone sits on the floor. Big enough to read from a metre away, with chalk on your hands.
ROUTINES
Build a routine from two kinds of step: an exercise step (name, sets, rest between them) or an interval step (work, rest, repeats). Presets are already on the shelf — HIIT 40/20, Tabata 20/10, EMOM 10, boxing rounds, stretch holds.
ON YOUR WRIST
Leave the phone in the locker. The Apple Watch app starts a rest or a preset routine from the wrist and feels every cue, with no phone nearby and nothing to wait for.
WHAT FREE MEANS HERE
Every mode. Unlimited runs. Five saved routines of your own, with the presets on top. The Watch app with every preset, phone in the locker. All the cues. Export whenever you like.
Timing is never locked. Not after one use, not after a week.
NO ADS. NO ACCOUNT. NO NETWORK.
Restbell has no account, no cloud and no tracking. There is nothing to sign up for, nothing to track, and nothing that leaves your phone. Your routines are yours, and you can export them to a file at any time.
RESTBELL PRO
Your own routines carried to your Apple Watch and kept current, plus unlimited saved routines.
Restbell Pro is an auto-renewing subscription, offered monthly or yearly with a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the current period ends; manage or cancel in Settings > Apple Account > Subscriptions.
