Your AirPods become an always-on posture coach. Posture watches your head position all day and gives you a gentle buzz when you slouch — no camera, no check-ins, all on-device and fully private.

No bloat, no sign-up. Calibrate once, wear your AirPods, and let Posture coach you all day.
Your AirPods read head position about 25 times a second in the background. Slouch for a while and you get a soft buzz. Straighten up and it goes quiet.
Build a daily posture streak. Freeze protection for off days. Watch your flame grow and stay motivated.
Stand tall, sit tall, then slouch on purpose. Posture learns your personal range in under a minute and scores every monitored minute against it.
Every monitored minute becomes your daily report: % of the day aligned, hour-by-hour rhythm, best stretches, and slouches caught.
Apple Watch adds background wrist-motion coaching and complications so posture help stays on your wrist.
See whether you're aligned, drifting, or slouching in real time. No need to open the app for a spot check.
See your posture score update in real time. Rings fill as you hold good posture, helping you build muscle memory.
Review past sessions, see your posture trends, and watch your average score improve over time.
Posture processes everything on-device. Your AirPods' head-motion data stays on your phone and is never recorded or transmitted. No accounts, no ads, and no posture analytics. Subscription status is validated through Apple StoreKit and RevenueCat (purchase receipts only). Your posture data is yours alone.

Most posture tools are one-time gadgets you forget about. I wanted something that lives on the devices you already carry — your iPhone, AirPods, and Apple Watch — and gently coaches you throughout the day without being annoying.
Posture turns the AirPods you already own into an always-on posture coach. Pop them in and Posture quietly watches your head position all day, giving you a gentle nudge the moment you settle into a real slouch. Your phone builds a daily report from how you actually sat, not spot checks.
Posture+ is a subscription with monthly and yearly plans plus a one-time lifetime unlock. A free trial is available on the subscription plans. $4.99/month, $29.99/year, or $79.99 lifetime.
AirPods Monitoring. All-day background head-motion monitoring via CMHeadphoneMotionManager. Get gentle nudges when your head angle drops below your calibrated baseline.
Apple Watch Integration. Background coaching on your wrist via the companion watch app.
Daily Reports & Streaks. Minute-by-minute posture aggregates, weekly trends, and Duolingo-style streaks with freeze protection.
