Rest Timer
Read full descriptionHide full description
Stop guessing how long to rest between sets. Tap a set done and a full-screen countdown fires on its own, then calls you back with voice, beep and haptic cues — so you start the next set at the right moment instead of scrolling your phone. Most gym timers are a generic stopwatch you have to remember to press. This one is built around the set: it arms itself from your training goal (strength 3 min, muscle 90 sec, endurance 45 sec, power 4 min), auto-starts the second you check a set off in your workout log, and keeps the screen awake so the numbers stay in front of you. Everything is stored on your device — no account, no sign-up. WHAT YOU GET - Never sit an extra two minutes by accident: rest starts by itself when you finish a set - Hear when to lift again without looking: voice cue, 3-2-1 beeps, halfway alert and haptics - Rest that matches your goal, not a random number: strength, muscle, endurance or power presets - One-tap presets from 30 seconds to 5 minutes, plus your own saved custom times - A full session log: exercises, sets, reps and kg, with running volume per workout - Proof you are consistent: rest-time and volume charts, goal split, day streak and levels PERFECT FOR - Lifters running straight sets who keep losing track of the clock - Beginners who want a science-backed rest length instead of guessing - Anyone rebuilding a routine and wanting sets, reps and weight in one place - Gym-goers who train with headphones in and need audio cues, not a screen WHY NOT JUST USE THE STOPWATCH APP? Because a stopwatch never starts itself, never knows you just finished a heavy triple, and never tells you when to go. Here the timer is wired to the set you just logged: check it off, rest runs, cues bring you back, and the session is recorded — instead of reset, restart and re-enter every ninety seconds. PRIVACY Everything lives on your iPhone. No account, no cloud upload, no ads, no tracking. FULL ACCESS Full access unlocks the whole app: auto-start rest timer, goal presets, custom saved times, workout logging with sets, reps and weight, full history, and the progress charts and streaks. Choose weekly, yearly, or a one-time lifetime purchase. Open the app, pick your training goal, and let your next rest run itself.
