Rack the bar, tap once, and lift again the second your rest is up. RestRound times the rest between your sets and taps you on the shoulder — right on the lock screen — the moment it ends, so you stop watching the clock and stop guessing. Most timers forget you the moment the screen locks. RestRound's countdown is anchored to real time, so you can pocket your phone, load plates, even let iOS kill the app — the end-of-rest alert still fires on the exact second, and it is marked time-sensitive so it cuts through your workout Focus mode. WHAT YOU GET • One tap on the ring starts your rest; −15 / +15 buttons adjust it mid-countdown when the rack tells you otherwise • A lock-screen alert the exact second rest ends — phone in pocket, app closed, Focus on, it still lands • A rest profile for every lift: 3:00 for deadlifts, 0:45 for curls — switch with one chip and the right countdown is already loaded • Superset and circuit modes: short rest inside the pair or round, full rest after it, without touching the settings mid-session • A set counter and session log, so you walk out knowing it was 24 sets, 41 minutes, average rest 1:38 • Charts that show your average rest, weekly gym time and rest discipline per muscle group — see when "90 seconds" quietly became three minutes PERFECT FOR • Lifters who rack the bar, glance at their phone, and resurface four minutes later mid-scroll • Strength programs where rest is prescribed — 3 minutes between squat sets is part of the program, not a suggestion • Superset and circuit training, where two different rest lengths alternate all session • Anyone tired of re-typing 1:30 into the Clock app between every single set WHY NOT JUST THE STOPWATCH? The stopwatch makes you do the math and remember to look. The Clock app makes you re-enter the time every set and its alarm ignores your Focus mode. RestRound remembers the right rest for each lift, restarts with one tap, counts your sets, logs every rest you take — and its alert is built to reach you mid-workout. PRIVATE BY DEFAULT Your lifts, sessions and stats stay on your iPhone. No account, no sign-in, no tracking, nothing leaves the device. FULL ACCESS RestRound Pro unlocks everything: unlimited lift profiles, superset and circuit modes, the full rest and gym-time statistics, and the two loudest alert tones. Choose a weekly subscription, a yearly subscription, or a one-time lifetime purchase — subscriptions auto-renew unless cancelled at least 24 hours before the period ends. Set your rest once. Let the next set come to you. Download RestRound and time today's session.
