Anterior Pelvic Tilt App: Free On-Device Coach

Your chair built this. It's called anterior pelvic tilt.

Sitting all day tips your pelvis forward — arched back, tight hips, that belly-out stance. NPT measures it, corrects it live with a standing coach, and trains it out with a daily program — no camera feed, no image, ever leaves your device.

/ Why it works

Three things, done well.

03 / 03

// 01

Live standing coach

Stand sideways and it speaks corrections bottom-up — knees, hips, ribs, head — praising each fix and anchoring you at neutral. No competitor app audibly fixes your posture in 15 seconds. This one does.

// 02

A real daily program

Reset → Build → Strengthen. Curated corrective exercises with animated form diagrams, a voice coach per set, and a conservative level-up after about two weeks.

// 03

Knows when to be quiet

On a call, on your phone, talking, or away from your desk — it knows, and stays silent. One alert per slouch episode, then a respectful quiet window.

/ What it measures

Five signals.
One live overlay.

Good · Poor · Scored

/ 01

Neck tiltThe angle your head leans forward or to a side while you work.

/ 02

Shoulder levelWhether one shoulder is sitting higher than the other.

/ 03

Head positionHow far your head drifts in front of your shoulders.

/ 04

Eye levelWhere your eyes sit relative to a healthy working line.

/ 05

Alignment scoreHips-over-ankles, ribs-over-pelvis, head and knees, scored as a percentage of body height.

A live skeleton overlay shows exactly what it sees.

Desk hours get a quiet good / poor status with skeleton overlay. Monthly check-ins run a guided snapshot with countdown auto-capture — no photo is ever stored.

Guided physio self-tests — the wall test and the Thomas test — come with animated diagrams and logged results, plus one-tap links to real demonstrations.

Watch your alignment score climb over weeks. Measured, not vibes.

Ten minutes, coached out loud.

Guided routine player — full-screen timers, prep countdowns, chimes, haptics, skip and pause.
Voice coach — spoken cues, halfway encouragement, praise per set, streak-aware send-offs.

// Desk — the work-hours companion

Watches your desk, not your calls.

Live posture monitor — neck, shoulders, head and eye level, checked continuously.
