See how much height you lose to slouching
A 60-second scan measures your Slouch Gap. Then 7-minute sessions train you to stand at your full height.
Built on your iPhone
Posture you can measure, on your own body
Start with a 60-second scan
Two numbers and one finding, all measured on you.
Slouch Gap
How much shorter you stand when you relax than when you stand tall, in centimetres.
Upright Score
A score from 0 to 100 for head position, shoulder level, head tilt and overhead reach.
Your top finding
One pattern, drawn on your own photo, like a head that sits forward of your shoulders.
A 28-day plan with dated rescans
Your plan is built from your scan. The Day 14 and Day 28 rescans are on the calendar from the start.
Coached by your camera, 7 minutes a day
Open, strengthen, practice. The camera counts reps, times holds and gives one cue at a time.

to your Day 28 rescan

What is the Slouch Gap?
How much shorter you stand when you relax than when you stand as tall as you can, in centimetres, measured on your own photos.
Do my photos leave my phone?
No. The scan runs on your iPhone. We keep landmarks and numbers, never photos.
How long does it take?
The scan takes about 60 seconds. Each daily session takes about 7 minutes.
Do I need equipment?
No. A resistance band or a foam roller adds options, and your plan uses what you have.
When do I rescan?
On Day 14 and Day 28. Both dates are on your plan from the first day.
Will it make me taller?
No. It shows how much height you lose to slouching and trains you to stand at your full height.
Is it a medical app?
No. PostureMax is a posture coach. It doesn’t diagnose or treat any condition.
Can I cancel?
Yes, anytime in your iPhone’s Settings. Cancel before the free week ends and you aren’t charged.
