Posture Trainer: Sit Straight

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 reminder 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 — gyroscope and accelerometer — track the angle you drift away from it. Prop the phone up on your desk or slip it into a chest pocket. No wearable, no camera, no extra kit. When you cross the tilt threshold you chose, you feel a calm double tap. Nothing else. No sound, no pop-up, no telling off. 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 (40° of tolerance) to Active (10°) - An adjustable gap between nudges, anywhere from 5 to 120 seconds - Quiet hours with start and end times that carry correctly past midnight - A stretch-break timer at 15, 30, 45 or 60 minutes, counting down on the Today screen - Master switches for haptics and alerts, so it all goes quiet in one tap - A live monitor showing pitch and roll, current deviation, elapsed time, good-posture time and alert count - Eleven guided routines across Neck, Shoulders, Back & Spine, Chest & Posture and Full Reset, each with named steps, a duration and a timed player - Insights: weekly upright percentage, the change in percentage points against last week, daily highlight cards, a seven-day consistency row, day streaks and totals - Session history saved on device — duration, good seconds, alerts and the threshold used — with swipe to delete - A Learn section with five written posture and ergonomics articles plus a cited source list - One daily reminder at 19:00, and full light and dark mode support PERFECT FOR - Desk workers and remote teams living in back-to-back video calls - Students hunched over laptops through long revision blocks - Anyone whose head is permanently tipped forward over a phone screen - 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 it 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.
