Exercise Counter · Reps + Sets

A rep counter for the gym,
sets advance on their own.

Set your target reps. Tap once per rep. When you hit the number, the set advances itself and the next one starts at zero — so the only counting your brain has to do is the weight on the bar.

Where reps get counted

Six places a rep counter beats your head.

Anywhere you need to count to twelve while also breathing, watching form in a mirror, and listening to a coach — the phone counts so the brain does not have to.

Section 01
01 / Strength training

Under the bar

Bench, squat, deadlift, row — phone propped on the bench, tap each rep, the set advances at 5 or 8 or 12 without you keeping count under load
02 / Calisthenics

On the mat

Pushups, pullups, dips, sit-ups — bodyweight sets where the rep count is the workout, not just a checkpoint along the way
03 / Physical therapy

Through the protocol

Rehab reps that have to be exact — 3 sets of 15 hip hinges, 2 sets of 10 band rows — the counter keeps the dose so you focus on form
04 / Group class

In the circuit

Coach a group through a four-station circuit — open multi-counter, one card per station, advance everyone together Open multi-counter →
05 / Home workout

In the living room

YouTube workout playing, dumbbells on the floor — phone on the coffee table, tap reps, the set count tracks the program without pausing the video
06 / Outdoor & boot camp

In the park

Park benches, pull-up bars, sandbag carries — works offline once loaded, vibrates on each rep so you do not have to glance down between burpees
What counting in your head never did

Four upgrades over a tally on the wrist.

Counting reps in your head works until it does not — set five, last rep, you forgot if it was 9 or 10. The browser version handles the four things every workout needs.

Section 02
01

Target reps + auto-advance sets

Set 12 reps, hit 12 reps, the set counter ticks up and the rep counter resets. No mental math, no glancing at a notebook, no losing count after a heavy single — just tap the rep and let the program run.

Auto
02

Vibration feedback per rep

Each rep buzzes, the completed set buzzes longer. You can lift with your eyes closed and still know the tap registered — the phone is a metronome, not a thing to look at between reps.

Haptic
03

Undo over-counts and ghost taps

Bumped the screen with a forearm in the rack? Hit Undo and the counter rolls back the last rep. If it advanced into the next set on a phantom tap, undo backs that out too.

04

Multi-exercise full-workout mode

A push day is bench, dips, overhead, lateral raises — open multi-counter, one card per movement, each with its own target reps and target sets. The whole workout is on one screen and saves automatically.

Multi
Side by side

Online exercise counter vs the alternatives.

A tally on the wrist, a notes app, and a programmed workout app all count reps. Each has a moment where they are the wrong tool for the lift in front of you.

About the tool

Exercise counter questions.

What people ask before counting reps in the browser — targets, undo, multi-exercise, offline use.

Section 04

Q.01 What is an exercise counter?

An exercise counter is a rep and set tracker for the device already in your hand at the gym. Tap the + button after each rep, hit the target, and the set advances on its own. The combined total — total reps and completed sets — is right there at the top of the screen between rounds.

Q.02 How do I set my target reps and sets?

Open the settings gear and pick your target reps per set (8, 10, 12, 15, or any custom number) and your target number of sets (3, 4, 5, etc.). The counter advances the set counter automatically when you hit the rep target — no math, no thinking, just lift.

Q.03 Does it vibrate when I complete a set?

Yes. On phones with vibration support, the counter buzzes each rep so you do not have to look at the screen, and gives a longer pulse when the set is complete. Eyes stay on form, hands stay on the bar.

Q.04 Can I undo an accidental tap?

Yes. Hit the undo button to roll back the last rep. If you over-counted into a new set, undo backs out of that too — including the auto-advance. Up to several steps of undo are kept, which is enough for any single set in a single workout.

Q.05 Can I track multiple exercises in one workout?

Yes. Open the multi-counter view and run one card per exercise — bench, squat, row, accessory work — each with its own target reps, target sets, and rep counter. The whole workout is on one screen and saves automatically.

Q.06 How is this different from a workout app?

A workout app is a whole programming + logging + analytics platform — great if you want to follow a 12-week program from your phone. This is a one-purpose rep counter for the moments where you just want to count to twelve without breaking rhythm. No account, no install, no scrolling through last week's back day.

Q.07 Does it work without WiFi at the gym?

Yes. Once the page loads, the counter runs entirely in your browser and saves every tap to the device — basement gyms, parking-lot bootcamps, hotel weight rooms with no signal all work the same. Add it to the home screen and it launches like an app.

Q.08 Is the workout history saved across devices?

The browser-based exercise counter on this page is free and saves locally to the device you are using. Workout history that syncs across devices, plus exports for a coach's spreadsheet, are part of the paid tier — useful if you split lifts between a phone in the morning and a tablet in the home gym.
