Download on the App StoreNo bloat, no sign-up. Free to start — upgrade for always-on monitoring.
Your AirPods' motion sensor reads your head angle in a quick three-second check. No camera, no glance at your phone.
Build a daily posture streak. Freeze protection for off days. Watch your flame grow and stay motivated.
Sit up straight once, and Posture learns what good looks like for your body. Every check-in compares you against your own baseline.
Posture watches your head angle silently all day and nudges you the moment you slouch — no need to open the app.
Apple Watch monitors your posture in the background and taps you when it's time to straighten up.
Posture+ runs quietly in the background. No need to open the app — just live your life and get nudges when you need them.
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 nudges you a few times a day with reminders, then a quick three-second AirPods check tells you if you're upright. Background AirPods monitoring and Apple Watch coaching add passive nudges for Posture+ subscribers. Three devices, one goal: better posture without thinking about it.
An optional upgrade for always-on coaching. $4.99/month, $29.99/year, or $79.99 lifetime, with a 7-day free trial.
AirPods Monitoring. Your AirPods detect head motion via CMHeadphoneMotionManager. Get gentle nudges when your head angle drops below your calibrated baseline.
Apple Watch Integration. Background monitoring via HKWorkoutSession on your wrist. Your watch taps you when it's time to straighten up — no phone needed.
Always-On Mode. Posture+ runs quietly in the background. No need to open the app or start a session. Just go about your day and get nudges when your posture slips.
All Free Features. AirPods check-ins, Duolingo-style streaks, calibration, live scoring, and your last 7 days of history are free forever.
