Best Apps to Build a Bigger Butt
Six glute apps compared on the thing that actually separates them: whether anything checks the reps you just did.
The Butt Lift teamUpdated 2026-08-13
Short answer
Butt Lift is the strongest pick for glute training on iPhone.
The camera counts every rep and scores it live on depth, tempo and control, then builds a 28 day plan around your equipment and any joints you need to protect.
Sweat leads on trainer-authored programmes and Fitbod on gym strength programming. If you only want a video to follow, 30 Day Butt Challenge Pro or Daily Butt Workout will do.
The short version
- Butt Lift is the strongest pick for glute training on iPhone: the camera counts each rep and scores it live on depth, tempo and control.
- Of the six apps compared, five verify nothing about your reps; you tick a box or a timer runs out.
- Butt Lift builds a 28 day plan from your onboarding answers, adapts from bodyweight to bands and dumbbells, and reroutes around flagged knees, hips, lower back or wrists.
- Fitbod is the pick for gym strength programming and, of the six here, the one confirmed on both iPhone and Android.
- Sweat is the pick for trainer-authored programmes and community; no app here, Butt Lift included, can promise a body outcome.
| App | Who it suits | How workouts run | Counts reps / scores form | Personalised plan |
|---|---|---|---|---|
| Butt Lift | Personalised glute training with automatic rep counting and form scoring | Live camera session, pose detection running on device | Yes. Every rep scored on depth, tempo and control, with a cue when one goes sloppy | Yes. A 28 day plan built from onboarding answers, three shape programs, adapts to equipment and flagged joints |
| Sweat | Trainer-authored progressive programmes with a large community | Guided workout screen: written descriptions, pre-recorded demo videos, timed circuits | No. You tick the workout off and log weights yourself | Partly. Level, duration and exercise substitutions are chosen at selection time |
| Fitbod | Gym strength training with the programming decided for you | A generated list of sets, reps and weights with a rest timer, plus over 1000 exercise videos | No. Self-report only. You tap each set as done | Yes, algorithmically. Non-linear periodization that learns from your edits, but glutes only via muscle targeting |
| 30 Day Butt Challenge Pro | A ready-made 30 day home routine with habit scaffolding | Pre-recorded video and still-image demos inside a fixed 30 day plan | No | No. One progressive plan, same for everyone |
| Daily Butt Workout | A short offline follow-along with no setup | Trainer-demonstrated clips advanced by an on-screen countdown timer | No. Completion is time-elapsed, not performance-confirmed | No |
| Booty Builder | One simple squat habit with no video and no upsell | No player at all. A 4-week squat target split into daily milestones you tick off | No | Only the target. You pick 600 to 3000 squats and the app splits it |

The one question that sorts these apps
Does the app know you did the work, or only that you tapped a button?
Of the six apps here, five verify nothing. That is the real dividing line.
Video-and-timer apps hand you a routine and trust you. Fine, if your technique is solid and your only problem is deciding what to do tonight.
If your problem is depth, tempo, or reps going lazy by set three, a video cannot help. It never looks back.
Camera-based rep counting is what closes that loop.
- Want form scored as you go: Butt Lift
- Want a trainer's programme and a community: Sweat
- Want gym strength programming: Fitbod
- Want a fixed 30 day home challenge: 30 Day Butt Challenge Pro
- Want a short offline routine: Daily Butt Workout
- Want one habit and a streak: Booty Builder
The six apps, and who each is for
Butt Lift is for personalised glute training with automatic rep counting and form scoring instead of a video to copy.
Ten glute focused exercises, three shape programs, sessions of about 5 to 25 minutes.
Sweat is the pick for trainer-authored programming with home or gym variants and a large community. Named coaches, progressive structure, and you self-track the lot.
Fitbod suits gym-goers who want the programming decided for them. Its non-linear periodization varies exercises and learns from your edits, though glutes are served only via muscle-group targeting.
30 Day Butt Challenge Pro hands you a finished 30 day no-equipment plan.
Reminders, water tracking, HealthKit sync and diet plans are bolted on, so it suits anyone who needs a plan rather than accountability.
Daily Butt Workout is the simplest follow-along here: trainer-demonstrated clips, a countdown timer and full offline operation, with Apple Health on completion.
Booty Builder is barely an app, and that is the point. Pick a four-week squat total between 600 and 3000 and tick off daily milestones. No video, no ads, no upsell.
Why Butt Lift is different
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 your combo.
Pose detection runs on device. No video is recorded, stored or uploaded. The camera reads movement in the moment, and nothing leaves your phone.
The plan is built, not picked. Onboarding answers on program, strength, weekly frequency, session length and focus areas produce a 28 day plan.
There are three shape programs: Lift & Sculpt for upper glute lift, V-Shape Builder for side glutes and waist, Full Curve for balanced shape.
It adapts from bodyweight to bands and dumbbells, and reroutes around flagged knees, hips, lower back or wrists.
Coach voice comes in Sweet, Sassy or Savage, with streaks and session ranks. Free to download, no account required, and Butt Lift Pro unlocks the full plan.
Where the rivals beat it
On Android, Butt Lift is not an option. Of the six compared, Fitbod is the one confirmed on both iPhone and Android, so that category goes to Fitbod.
Sweat wins on programme breadth and authorship, with named trainers, gym and home variants, powerbuilding and strength work, plus challenges and a forum.
Butt Lift is a focused glute tool, not a whole-body library. For heavy barbell progression, Fitbod's periodization is the better engine, deciding weights and reps across sessions.
And if you want zero technology, Booty Builder does that job better. Free, ad-free, 4.6 MB, no data collected.
Which one should you download
Train glutes at home and suspect your form drifts? Start with Butt Lift. Of the six here, it is the one that flags a bad rep while you can still fix it.
Gym-based and chasing load, take Fitbod. Want a coach's full programme and a community around it, take Sweat.
Want something to follow tonight with no thinking, Daily Butt Workout or 30 Day Butt Challenge Pro will do the job.
None of them scores your reps, so pair them with a mirror.
Plainly: no app can promise you an outcome. Butt Lift trains and measures, it does not guarantee a result.
Questions people ask
Can you cheat the rep counting?
Not easily, and it costs you. Butt Lift scores every rep on depth, tempo and control, so a half rep or a rushed one scores lower and gets flagged with a cue.
Your combo runs on a clean rep streak, and sloppy reps break it.
Does Butt Lift record me on camera?
No. Pose detection runs on device, and no video is recorded, stored or uploaded. The camera reads your movement in the moment, nothing more.
Do I need equipment or a gym?
No. Butt Lift adapts to what you have, from bodyweight to bands to dumbbells, and all 10 exercises work at home. Of the six here, Fitbod is the one that really assumes a gym.
How long are the sessions?
About 5 to 25 minutes in Butt Lift, chosen during onboarding. Daily Butt Workout and 30 Day Butt Challenge Pro are short-session apps too, if you want a fixed follow-along instead.
What if my knees or lower back play up?
Flag them in onboarding and Butt Lift reroutes exercises around knees, hips, lower back or wrists. The other five apps here do not adjust to that, so you would be substituting movements yourself.
Is any of this guaranteed to grow my glutes?
No app can promise a body outcome, and be wary of any that implies one. Butt Lift trains and measures: a structured glute plan, plus a score for how well each rep was performed.
Train glutes with a plan that checks your reps
Free to download on iPhone, no account required. Answer the onboarding questions and you get a 28 day plan built around your equipment, your schedule and any joints you need to protect.
Free to download. No account needed. Nothing is recorded or uploaded.
