Heighten: Posture Scan and Coach to Stand Taller
Your posture is hiding some of your height. Stand at your full height.
Heighten is a posture scan for your iPhone: two photos give you a Posture Score and an estimate of the height your slouch is hiding, then a daily plan coaches you to stand taller. A posture app that measures against you, not against a stranger's ideal.

Stand in front of the camera, turn to your side, and get a clear Posture Score with plain-language observations such as your head sits forward of your shoulders, instead of jargon. The posture scan reads forward head posture, rounded shoulders and uneven hips, the patterns behind tech neck and, over the years, a neck hump.
See the height slouching hides
Heighten estimates how much height your current stance is hiding, from two angles in your side photo over an average neck and torso length, capped at 4 cm, then watches the number shrink as your posture improves. You will not grow a millimeter, but you will stand at your full height.
Fix posture with a posture workout built from your scan
Every day gets a short corrective routine assembled from your own results, neck exercises like chin tucks beside chest openers, focused on what you actually need: opening the chest, bringing the head back over the shoulders, leveling the base. Posture correction only sticks when it starts from your own body, so there is no generic stretching list here. Five minutes, no equipment, and your music keeps playing while you train. A posture corrector with nothing to strap on.
A desk coach that notices the slouch
With supported AirPods in, start a desk session and they notice the moment you begin to sink. Sit tall for a few seconds to set your personal baseline, then work as usual; a gentle chime brings you back upright. It is a posture reminder that fires only when you actually slouch, never on a timer, and it pauses honestly when it cannot watch. Desk sessions come with the subscription and need earbuds that sense head motion: AirPods (3rd generation), AirPods Pro, AirPods Max and the other supported models listed in the app. Other earbuds cannot.
A posture tracker that measures against you
Rescan and see your score climb against your own starting point. Keep the streak alive with the daily routine, check your session history to see how upright your desk hours really are, and share your score when you are proud of it. Stand up straight and improve posture: you will not grow a millimeter, but you will stand at your full height.
Stand taller, on your terms
Heighten is a posture app that keeps your photos and scans on your phone: they never leave your iPhone, the analysis runs on the device, and the daily reminder names the exercise waiting for you instead of nagging. Alignment observations, not medical advice; for pain or concerns, see a professional.

Stand in front of the camera, turn to your side, and get a clear Posture Score with plain-language observations like your head sits forward of your shoulders, instead of jargon. The scan reads forward head posture, rounded shoulders and uneven hips, the patterns behind tech neck, or text neck if that is the name you know it by, and, over the years, a neck hump or dowager hump. The height figure is an estimate, worked out from two angles in your side photo over an average neck and torso length and capped at 4 cm; watch it shrink as your posture improves. As a forward head posture app it names the thing most people carry for years without ever being told.

Straight answers.
Is Heighten medical advice?
No. Heighten shares alignment observations, not medical advice. For pain or concerns, see a professional.
What does the scan need?
Two photos, front and side, taken with your iPhone. No equipment and nothing to strap on.
Do I need special earbuds?
Only for desk sessions, which come with the subscription and use supported AirPods models that sense head motion to notice when you sink. The scan, the score and the daily routine work without them.
Do my photos leave my phone?
No. The analysis runs on your iPhone and your photos and scans stay there.
How is the height number worked out?
It is an estimate: two angles in your side photo, ear against shoulder and shoulder against hip, over an average neck and torso length, capped at 4 cm. It shows how much height your posture may be hiding, never growth, and it does not change your bones.
Stand at your full height.
Two photos tonight, a straighter you at the next mirror.
