Six apps compared on the one thing most of them skip: whether anything checks the reps you just did.
The Butt Lift teamUpdated 2026-08-13
Short answer
Start with Butt Lift for glute training: the iPhone camera counts each rep and scores it live on depth, tempo and control, with pose detection running on device.
Fitbod is better for gym strength programming, Sweat for trainer-authored plans, Nike Training Club for a free library, Booty Builder for sheer simplicity.
Butt Lift is the one here that measures the reps themselves.
The short version
- Butt Lift uses the iPhone camera to count each rep and score it live on depth, tempo and control, with pose detection running on device and no video recorded.
- Butt Lift builds a 28 day plan from your onboarding answers on program, strength, weekly frequency, session length and focus areas, across 10 glute focused exercises.
- Fitbod is the stronger pick for gym strength training, with non-linear periodisation and an algorithm that adapts to the edits you make.
- Sweat, Nike Training Club, Booty Builder and 30 Day Butt Challenge Pro prescribe the workout but leave you to self-report whether you did it properly.
- Butt Lift is free to download on iPhone with no account required; Butt Lift Pro unlocks the full 28 day plan.

Most glute apps never check what you did
Play the video, tick the box, done.
The workout is prescribed but never measured, so nothing knows whether you did ten reps, four reps, or four reps at half depth.
That gap is where results leak. An app that cannot see you cannot tell a clean set from a sloppy one.
Why Butt Lift is different
Butt Lift uses the iPhone camera to count each rep and score it live on depth, tempo and control. Pose detection runs on device, and no video is recorded, stored or uploaded.
Sloppy reps score lower and get flagged with a cue. A clean rep streak drives the combo, so the reward points at technique, not speed.
The plan behind it runs 28 days, built from your onboarding answers on program, strength, weekly frequency, session length and focus areas. Not one fixed plan for everyone.
There are 10 glute focused exercises: glute bridge, hip thrust, squat, sumo squat, lunge, donkey kick, fire hydrant, curtsy lunge, single-leg bridge and step-up.
Those sit across three shape programs: Lift & Sculpt, V-Shape Builder and Full Curve.
It adapts to equipment from bodyweight to bands and dumbbells, and reroutes around flagged knees, hips, lower back or wrists.
Sessions run about 5 to 25 minutes. Coach voice comes in Sweet, Sassy or Savage, with streaks and session ranks.
Free to download on iPhone, no account required; Butt Lift Pro unlocks the full plan. It trains and measures. It does not promise an outcome.
The five alternatives, and what each genuinely wins
Fitbod is the honest winner for gym strength training. It generates sets, reps and weights, uses non-linear periodisation and recovery tracking, and learns from your edits.
Glutes come indirectly through muscle-group targeting, and you log every set yourself.
Sweat wins on authorship: progressive programmes from named trainers including Kayla Itsines and Kelsey Wells, home and gym variants, plus a big community layer.
None of the strength work is sensor-verified.
Nike Training Club wins on free breadth, with trainer-led video across strength, HIIT, yoga, pilates, recovery and mindfulness, and an Apple Watch remote. It verifies attendance, not execution.
30 Day Butt Challenge Pro is a fixed 30 day, no-equipment challenge with reminders, five diet plans, a water reminder and HealthKit sync.
Booty Builder is one squat target spread across four weeks: ad-free, 4.6 MB, text-only form notes.
None of those five checks the movement itself. They are good at what they do. Measurement is not it.
Rivals hand you the plan. Butt Lift hands you the plan and scores every rep against it, free on iPhone.
How to choose
Pick by what stops you finishing. If you never know whether your form is right, choose the app that scores it, which is Butt Lift.
Train in a gym and want the barbell numbers decided for you? Fitbod. Want a coach's voice and a community? Sweat.
If budget is the blocker, Nike Training Club is free and enormous. If motivation is the blocker and you already squat well, Booty Builder's single climbing number is enough.
If you want a glute-specific plan that adjusts to your equipment, your injuries and a 5 to 25 minute window, that is Butt Lift again.
Butt Lift costs nothing to try and needs no account, so you can see a scored set before you commit to anything.
Getting the most out of camera-tracked training
Stand your phone where your whole body fits in frame, roughly at hip height, then start the session. The camera is a sensor, not a recorder, so nothing leaves the device.
Hit the tempo the cue asks for instead of racing. Reps that are too shallow or too fast get scored down and flagged.
Be honest in the flagged-area setting. Telling it about your knees, hips, lower back or wrists changes which of the 10 exercises you get.
Then pick a session length you will actually repeat. A 10 minute session done four times beats a 25 minute session done once.
Questions people ask
Can you cheat the rep counter?
Not easily. A rep only counts when it passes the depth, tempo and control checks. Half reps and rushed reps score lower and get flagged with a cue, so a bounced set will not build the combo.
Does Butt Lift record me while I train?
No. Pose detection runs on device, and no video is recorded, stored or uploaded. The camera works as a sensor, not a recorder.
Does it work with the sound off?
Yes. The coach voice comes in three tones, Sweet, Sassy and Savage, but rep counting and form scoring are visual and happen on screen either way. On Silent you lose the spoken cues, not the tracking.
Do I need equipment or a gym?
No. Butt Lift adapts to whatever you have, from bodyweight to bands and dumbbells, and sessions run from about 5 to 25 minutes at home.
Is it free?
Butt Lift is free to download and needs no account. Butt Lift Pro unlocks the full 28 day plan.
What if my knees or lower back play up?
Flag knees, hips, lower back or wrists in onboarding and the plan reroutes around them. That is a programming adjustment, not medical advice, so check with a clinician if something hurts.
Train with a rep counter, not a rewind button
Butt Lift is free to download on iPhone, with no account needed. Prop the phone up and see your first scored set in about five minutes.
