New: a rebuilt rep scanner. Live count and graph, push-ups and muscle-ups, sessions that count through rests, and 9:16 videos of your sets.
Build the back you actually want, and climb to 50 pull-ups in a row. BackMaxx scans your back with AI, builds a plan around what's lagging, runs a day-by-day pull-up program, and counts every rep with your camera.
TODAY: WHAT TO DO, IN ONE SCREEN
Open the app and Today shows exactly what's next: your pull-up day, your back session, or what to do on a rest day, each with the button that starts it. Doing both? Back sessions leave pull-ups to the program, so the two never double up.
50 PULL-UPS PROGRAM
From your max today to 50 strict pull-ups in a row. Your max picks one of 11 tiers; each tier is 6 or 9 training days of 5 sets with rest days built in, then a retest that picks your next tier. Type the max you already know and Day 1 starts today, or test it with the camera. Missed a target? Choose where to pick the tier back up: Day 1, three days back, or retry the day. A calendar shows every session and test ahead.
A CAMERA THAT COUNTS EVERY REP
Prop your phone up and pull. A big live count, a shoulder-height graph and your pace, speed and time fill the screen, and every rep is counted out loud and judged: chin over the bar, arms straight at the bottom. Kipping, swinging and half reps are flagged, so your number is honest. Then see range of motion, pull speed and tempo for the set. It counts muscle-ups and push-ups too, and can keep counting through your rests for one total across a long session, or stop at a target. The camera is analyzed on your iPhone and never uploaded.
SHARE YOUR SETS
Turn on Replay and any set becomes a vertical 9:16 video with the scanner drawn over it, ready to post. You can also run a clip from your Photos through the scanner. Replays stay on your iPhone unless you share them.
YOUR BACK SCORE
One photo with the selfie camera and a 5-second self-timer. The AI scores six back zones and eight individual muscles 0-100, lights them up on a muscle map, and names your strongest zone and your priority. Climb nine ranks from Newbie to GOAT.
A PLAN BUILT ON YOUR WEAK ZONES
Your program comes from your scan, your goals, your gym or home kit and how many sessions a week you can train, with extra volume where you need it most, form cues on every movement and progressive overload targets. Dial any session to Easy, Standard or Hard, or build a 15-minute express session.
GUIDED SESSIONS
Warm-up, main work, cool-down. 124 back exercises, each with an animated guide, one lift at a time, rest timers that count you back in, swaps for the kit you have, personal records celebrated.
PROVE IT'S WORKING
Re-scan weekly: watch your score and rank climb, compare before/after photos and see your plan re-balance as zones catch up. Streaks, XP and trophies track every set, program day and rest day.
BUILT PRIVATE
Scan photos are analyzed transiently and never stored on our servers. Progress photos and rep scanner video stay on your device. No account required. No ads.
Scores are visual estimates for training motivation, not medical measurements or advice.

A rebuilt rep scanner, made to be filmed.
- A big live count, a shoulder-height graph, and your pace, speed and time on screen as you go.
- It counts muscle-ups and push-ups too, and can keep counting through rests: one total for a long session, or stop at a target.
- Turn on Replay to export any set as a 9:16 video with the scanner on it, or run a clip from Photos through it.
- Strict pull-ups filmed from the front or from a low camera are no longer marked as kipping.
- 47 new back exercises, each with its own animated guide, so your plan draws from 124. Bench lifts only when your kit has a bench.
