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.

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.

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.

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

Neck tilt: The angle your head leans forward or to a side while you work.
Shoulder level: Whether one shoulder is sitting higher than the other.
Head position: How far your head drifts in front of your shoulders.
Eye level: Where your eyes sit relative to a healthy working line.
Alignment score: Hips-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.

Inside the app

Four tabs. One habit.

Today · Desk · Progress · Learn

Today — the daily coach

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.
Streaks & week dots — a day streak and a last-7-days view that keeps the habit visible.

Desk — the work-hours companion

Watches your desk, not your calls.

Live posture monitor — neck, shoulders, head and eye level, checked continuously.
Sitting-break coach — a spoken nudge past 40 minutes seated; standing for 2+ minutes auto-logs the break.
8 micro-breaks — standing resets and two in-chair drills, all animated.

Progress — proof it's working

Results, not screenshots.

Check-in trends — alignment scores over weeks, with deltas per metric.
Streak calendar — sessions, minutes trained, and your best streak.
Desk insights — your top posture issues and how they trend by time of day.

Understand the why.

APT education — what anterior pelvic tilt is, why sitting feeds it, and the red flags to know.
876-exercise library — searchable by muscle and level, with photos and instructions.
Not medical advice — built for everyday posture habits, not diagnosis or treatment.

Private by architecture

Your camera never leaves your device — and that's verifiable.

100% on-device: no account, no server, no analytics, and no image is ever stored. Open your browser's dev tools and watch the network tab stay silent while it runs. Turn on airplane mode — nothing changes.
