Tap or press Space to count reps for the set you're on, finish the set to log it, and let the rest timer count you down to the next one.

Losing count mid-set is the easiest way to shortchange a workout, and typing numbers into a notes app between reps breaks your rhythm.
Tap the screen or hit Space with a free hand so you can keep your eyes on your form, not on typing.
The rest timer starts the moment you finish a set, so you never have to glance at a phone clock between sets.
Every finished set is tallied automatically, so your workout total is accurate without manual math.
Rep counting sounds trivial until you're on rep 14 of a set of high-fatigue squats and lose your place because your phone buzzed. This tool keeps the interaction to a single motion — a tap or a spacebar press — so counting never competes with your attention on form or breathing. Each set you finish is stored in the current session, and the running totals in the settings panel update automatically, so you always know how many sets and total reps you've logged without doing mental addition mid-workout. The rest timer exists for the same reason lifters use rest intervals in the first place: consistent rest between sets is what makes strength and hypertrophy programs comparable week to week, and eyeballing a clock is a common source of drift. Because the countdown runs with the Web Audio API, it can chime when your rest ends even if you've set the screen down, so you don't have to babysit a timer between exercises. Session history is stored locally in your browser using localStorage, which means it persists across visits without any account, login or server, and it also means it's private to your device — nothing about your workout is ever uploaded anywhere.
Tap or spacebar — no menus or number pads to fumble with mid-set.
An audible cue tells you exactly when rest is over, so intervals stay consistent.
History lives in your browser's local storage only; nothing is sent to a server.
Tap the big counter button or press the spacebar each time you complete a rep. The number updates instantly with no page reload.
It locks in your current rep count as a completed set, adds it to today's session list, resets the counter to zero for the next set, and starts the rest timer if auto-rest is enabled.
Yes. Enter any rest duration in seconds in the settings panel. You can also add 15 seconds or skip the rest entirely while it is counting down.
Yes. Each finished session, including the date, number of sets, reps per set and total reps, is saved to your browser's local storage so you can review past workouts until you clear the history.
Yes. It plays an audible tone generated with the Web Audio API when the rest period ends, so you don't have to watch the screen while resting.
