You never notice the moment you start to slouch. Your head drifts forward, your shoulders round, and forty minutes later your neck is aching. PosturePing catches that moment for you and nudges you upright before the strain adds up. Most posture apps are just a repeating timer that buzzes whether you are sitting tall or folded over your laptop. PosturePing actually measures. You set a baseline in your good, upright position with one tap, and the motion sensors already inside your iPhone watch the angle you drift away from it. Prop the phone up on your desk or slip it in a chest pocket — no wearable, no camera, no extra hardware. When you cross the tilt threshold you chose, you feel a calm double-tap. Nothing else. No sound, no popup, no shame. WHAT YOU GET - A nudge that fires when you are actually slouching, not on a blind schedule - One-tap calibration that teaches the app your own upright position - A sensitivity dial from Gentle to Active, so you decide how much drift is too much - Quiet hours and an adjustable alert gap, so it never buzzes during a meeting or at midnight - Eleven guided neck, shoulder, chest and back routines that undo the desk hunch in under a minute - Weekly upright-time percentage, daily highlights, streaks and session history so you can watch the habit form PERFECT FOR - Desk workers and remote teams living in back-to-back video calls - Students hunched over laptops through long study blocks - Anyone with tech neck from hours of looking down at a phone - People rebuilding a posture habit after a stiff, painful week WHY NOT JUST SET A PHONE ALARM? Because a timer has no idea what you are doing. It interrupts you when you are already sitting perfectly, then stays silent through the twenty minutes you spent collapsed over your keyboard. A reminder you learn to ignore changes nothing. PosturePing only speaks up when your angle says it should, which is why the nudge still works after week one. PosturePing reads device tilt as a proxy for posture to help you build a healthier sitting habit. It is not a medical device and does not diagnose, treat or cure any condition. PRIVACY Everything runs on your device. Sessions, baselines and streaks are stored locally on your iPhone — no account, no sign-up, nothing to sync. The app works completely offline. FULL ACCESS One purchase unlocks all of PosturePing: every guided stretch routine, custom sensitivity, alert cadence and quiet hours, plus full session history, streaks and weekly posture insights. Choose the weekly plan, the yearly plan, or a one-time lifetime purchase — yearly and lifetime cost far less over time. Prices appear in your local currency before you confirm. Calibrate once today, work one normal afternoon, and see what your upright percentage really looks like.
