Best 28-Day Glute Workout Apps for iPhone, Compared
Six iPhone glute apps, compared on the thing that really differs between them: whether anything checks the rep you just did.
The Butt Lift teamUpdated 2026-08-14
Short answer
Butt Lift is the pick for a 28 day glute plan that counts your reps and scores form live, using the iPhone camera on device with nothing recorded.
Of the six compared, Sweat has the deepest trainer-authored programmes, Daily Butt Workout runs without a signal, Booty Builder is a free squat streak, and 30 Day Butt Challenge Pro handles habit tracking and HealthKit.
The short version
- Of the six 28 day glute apps compared, Butt Lift is the one that counts reps and scores form live through the iPhone camera; the other five rely on self-reporting.
- Butt Lift's pose detection runs on device, and no video is recorded, stored or uploaded.
- Sweat has the deepest trainer-authored library here, with named trainers and home and gym variants, but nothing in it is sensor-verified.
- Daily Butt Workout is the option that runs fully offline, and Booty Builder is free, ad-free and squats only.
- Four weeks is enough to build a habit and raise rep quality; none of these apps should promise a specific physical result in 28 days.

The thing that actually separates these apps
Nearly every glute app does the same job. It plays you a video and trusts you did it.
Of the six compared here, Butt Lift is the one that checks the rep you actually performed.
The other five measure time elapsed, a tick box, or a number you typed in yourself.
So the useful question is not how many workouts are bundled in. It is whether the app knows a full hip thrust from a lazy one.
The apps, and who each one genuinely suits
Butt Lift builds a 28 day glute plan from your onboarding answers: program, strength, weekly frequency, session length and focus areas.
It is free to download, with Butt Lift Pro unlocking the full plan. No account required.
Sweat has the deepest library here, authored by named trainers including Kayla Itsines and Kelsey Wells, with home and gym variants.
Nothing in Sweat is sensor-verified. You mark workouts complete and log weights by hand.
30 Day Butt Challenge Pro wraps a video-led challenge in habit features: reminders, a water reminder, a transformation tracker, five diet plans and full HealthKit sync.
Completion is self-reported by marking the day done.
Daily Butt Workout is deliberately plain: clips, an on-screen countdown, no signal needed. Every exercise is demonstrated by a certified personal trainer.
Booty Builder is just squats. Pick a total from 600 to 3000 over four weeks and tick off daily milestones.
It is free, ad-free, 4.6 MB, with no data collected, and there is no video in it.
BootyFit runs a no-equipment 28 day arc with beginner to advanced levels.
Its listing never says whether sessions arrive as video, animation or a timer.
- Butt Lift: camera rep counting and live form scoring
- Sweat: breadth and authorship, self-tracked
- 30 Day Butt Challenge Pro: habit features and HealthKit
- Daily Butt Workout: offline video and timer
- Booty Builder: one exercise, one streak, free
- BootyFit: fixed beginner programme, delivery unclear
Why Butt Lift is different
Butt Lift owns one thing: personalised glute training with automatic rep counting and form scoring, not a video to copy.
The iPhone camera counts each rep and scores it live on depth, tempo and control.
Sloppy reps score lower and get flagged with a cue, and a clean rep streak drives the combo.
On the camera and privacy: pose detection runs on device and no video is recorded, stored or uploaded.
The 28 days are not identical for everyone. Three shape programs, Lift & Sculpt, V-Shape Builder and Full Curve, sit on top of the frequency and session length you choose.
Ten glute focused exercises cover it: glute bridge, hip thrust, squat, sumo squat, lunge, donkey kick, fire hydrant, curtsy lunge, single-leg bridge and step-up.
It adapts from bodyweight to bands and dumbbells, and reroutes around flagged knees, hips, lower back or wrists.
Sessions run about 5 to 25 minutes. The coach voice comes in Sweet, Sassy or Savage, with streaks and session ranks.
Butt Lift trains and measures; it does not promise a result.
How to choose in one minute
Want a coach and a library? Take Sweat. Of the six here, it has the widest programme range and the named-trainer authorship, and plenty of people train perfectly well self-tracking.
Train where there is no signal? Take Daily Butt Workout. It runs fully offline, which a camera-led session cannot match in a basement gym.
Want zero cost and zero friction? Booty Builder. Free, ad-free, no data collected, and the whole app is squats.
Want scaffolding around the workout? 30 Day Butt Challenge Pro, for the HealthKit sync, reminders and tracker.
Pick Butt Lift when the missing piece is not motivation or variety, but knowing whether the reps you just did were any good.
Getting through the 28 days
Four weeks is long enough to build the habit and improve rep quality. That is the honest thing to measure.
Set a session length you will actually do, 5 to 25 minutes, not the one that looks impressive on day one.
Flag any dodgy joints before you start, so the plan routes around them instead of you skipping days.
Judge progress on the scores, not the mirror. A rising clean rep streak is a real signal; a four week body change promise is not.
Questions people ask
Can you cheat the rep counter?
Not easily. Every rep is scored on depth, tempo and control, so half reps and rushed reps score lower and get flagged with a cue instead of banked. Clean reps drive the combo.
Does it record me while I train?
No. Pose detection runs on device, and no video is recorded, stored or uploaded.
Does it work with the phone on Silent?
The coach voice is audio, so keep sound on if you want the spoken cues in Sweet, Sassy or Savage. Rep counting is camera based, so it carries on regardless.
Do I need equipment for 28 days?
No. Butt Lift adapts from bodyweight only up to bands and dumbbells. The other apps here are largely no-equipment by design too.
What if my knees or lower back play up?
Flag them in onboarding and the plan reroutes around flagged knees, hips, lower back or wrists. It trains and measures, it does not diagnose, so anything painful is a doctor question.
Is 28 days long enough to see anything?
Long enough to build the habit and to watch your rep quality climb, which is what the form score tracks. None of these apps should promise a specific physical outcome in four weeks.
