Best Workout Apps That Count Your Reps

One app on this list watches you move. The other five ask you to tick a box.

12 of 15 reps FORM 92% Depth, tempo and control, scored live On device. No video leaves your phone.

Short answer

Butt Lift counts your reps: the iPhone camera counts each one and scores it live on depth, tempo and control.

Fitbod, Nike Training Club, Sweat, 30 Day Butt Challenge Pro and Daily Butt Workout are good apps, and none of them counts reps automatically. You tap a set as done. That is a log, not a count.

The short version

  • Butt Lift is the one app in this comparison that counts reps automatically: the iPhone camera scores every rep live on depth, tempo and control.
  • Fitbod, Nike Training Club, Sweat, 30 Day Butt Challenge Pro and Daily Butt Workout all rely on you logging sets or ticking a workout complete.
  • Butt Lift builds a 28 day plan from your onboarding answers on program, strength, weekly frequency, session length and focus areas, and reroutes around flagged knees, hips, lower back or wrists.
  • Pose detection runs on device in Butt Lift: no video is recorded, stored or uploaded, and no account is required.
  • Fitbod is the stronger pick for loaded barbell and dumbbell programming, Nike Training Club for a free video library, and Sweat for trainer-authored programmes for women.

What "counts your reps" actually means

Nearly every app here is a logbook with videos bolted on. Watch the demo, do the work, tell the app you did it.

So the completion tick measures your honesty, not your effort. A half-depth squat and a perfect one look identical in the data.

Counting is a different job. Something has to watch the movement and decide whether it happened.

On iPhone that means the camera plus on-device pose detection. Everything else is self-report.

How camera rep counting works: the phone tracks joint points on device, scores each rep on depth, tempo and control, then counts it clean or counts it low with a form cue. Self-reported logging skips every check in the middle.

The six apps, and what each one actually does

Butt Lift counts every rep with the iPhone camera and scores it live on depth, tempo and control.

It is free to download. Butt Lift Pro unlocks the full plan, and no account is required.

Fitbod picks the programming for you: which muscles, what weight, how many reps, across over 1000 exercises with multi-angle demos.

You log every set by hand.

Nike Training Club is a large free library of trainer-led video classes, whiteboard workouts and multi-week programs, with an Apple Watch companion.

Completion is self-logged.

Sweat runs trainer-authored progressive programmes from named coaches including Kayla Itsines and Kelsey Wells, home or gym.

Sets are self-reported.

30 Day Butt Challenge Pro is a fixed 30 day no-equipment plan with HealthKit sync, diet plans and a transformation tracker.

Nothing about the exercise itself is measured.

Daily Butt Workout is video plus timer, fully offline, every exercise demonstrated by a certified personal trainer.

The timer runs whether or not you do.

Why Butt Lift is different

The phone counts the rep instead of you. Pose detection runs on device, and no video is recorded, stored or uploaded.

Every rep is scored live on depth, tempo and control. Sloppy reps score lower and get a cue, and a clean rep streak drives the combo.

The plan is built, not decorative: a 28 day plan from your onboarding answers on program, strength, weekly frequency, session length and focus areas.

There are three shape programs: Lift & Sculpt for upper glute lift, V-Shape Builder for side glutes and waist, Full Curve for balanced all-round shape.

It adapts to bodyweight, bands or dumbbells, and reroutes around flagged knees, hips, lower back or wrists.

Sessions run from about 5 to 25 minutes, chosen in onboarding.

Coach voice comes in Sweet, Sassy and Savage, with streaks and session ranks. Butt Lift trains and measures; it does not promise an outcome.

Where the rivals genuinely win

Fitbod owns gym barbell and dumbbell programming. Non-linear periodization and recovery tracking beat anything camera-based for a loaded barbell session.

Nike Training Club owns free breadth. Strength, HIIT, yoga, pilates, recovery and mindfulness, produced properly, at no cost.

Sweat owns trainer-authored programme depth for women, with named coaches, progressive structure and a large community.

Train offline, or refuse subscriptions? Daily Butt Workout is the pragmatic answer, and it is honest about being a timer.

Which one should you download

Barbell work in a gym, with the programming solved for you: Fitbod.

Variety on a zero budget: Nike Training Club. A coach-authored programme with a community behind it: Sweat.

Glutes specifically, with proof that each rep was actually performed to depth, on a plan shaped around your equipment, injuries and available minutes: Butt Lift.

If your last plan stalled because nothing checked your form, a bigger video library will not fix that.

Questions people ask

Can you cheat the rep counter?

Not easily. A shallow or rushed rep scores lower on depth, tempo and control, gets flagged with a cue, and breaks your clean rep streak.

Does Butt Lift record video of me?

No. Pose detection runs on device. No video is recorded, stored or uploaded, and nothing leaves your phone.

Do any of the other apps count reps?

No. Fitbod has you enter sets and reps yourself. Nike Training Club, Sweat, 30 Day Butt Challenge Pro and Daily Butt Workout rely on you marking a workout complete, or on a timer running out.

Do I need equipment?

No. Butt Lift adapts to what you have, from bodyweight to bands and dumbbells.

The ten exercises are glute bridge, hip thrust, squat, sumo squat, lunge, donkey kick, fire hydrant, curtsy lunge, single-leg bridge and step-up.

What if my knees or lower back are dodgy?

Flag them in onboarding. Butt Lift reroutes exercises around flagged knees, hips, lower back or wrists. Sessions run from about 5 to 25 minutes, so pick a length you will actually finish.

Is there an Android version?

No, Butt Lift is iPhone only. On Android, Fitbod is the honest recommendation for structured strength training.
