Posture Alert
Read full descriptionHide full description
Your AirPods already know when you slouch. Posture Alert just tells you. No camera. No wearable to buy. No sensor to strap on. Posture Alert reads the motion sensors already inside your AirPods, learns how you sit when you sit well, and gives you a gentle nudge the moment you drift out of it. HOW IT WORKS 1. Pop in your AirPods and sit the way you want to sit. 2. Tap Start. That posture becomes your baseline. 3. Slouch for longer than your chosen hold time and you get a nudge — a sound, a notification, or both. WHAT YOU GET • Live posture tracking that runs quietly in the background • Nudges you can tune — how far you can lean, and how long before it speaks up • 20-20-20 eye breaks: every 20 minutes, look 20 feet away for 20 seconds • Lock Screen Live Activity showing your status and elapsed time at a glance • Built-in reminder sounds, or record your own instead of another generic beep • A full history of every session, grouped by day • Progress charts: your posture over time, when you slouch most, how long you last BUILT TO STAY OUT OF THE WAY Everything runs on your device. Your posture data never leaves your iPhone — there is no account to create and nothing to sign in to. Start a session, put the phone down, and get on with your work. REQUIRES AIRPODS Posture Alert needs AirPods (3rd generation or later), AirPods Pro, AirPods Max, or Beats with motion sensors. It cannot measure your posture without them.

Sit tall through a focus block — without a coach nagging you. Pillar reads head and neck position from the motion sensors in your AirPods and quietly tells you when you slouch. No camera. No wearable to buy. No photo of you. HOW IT WORKS • Put your AirPods in and start a session — open-ended, or a Pomodoro focus/break block. • Pillar measures your own tall and slouched angles once, so the threshold is yours rather than a population average. • While you work it watches your head pitch. When your head drops forward and stays there, you get a quiet haptic or a soft cue. The moment you straighten, it stops. • At the end you get a score for the session — and over weeks, the trend and one pattern worth acting on. WHY IT WORKS THIS WAY Posture and focus are one loop. The Pomodoro timer is the reason to keep the AirPods in, and the AirPods are the reason the timer knows you slouched. WHAT'S INSIDE • Live posture reading during a session, calculated on your iPhone • Nudges that escalate gently and back off when you respond • Pomodoro focus and break cycles, scored cycle by cycle • A daily tall-time goal and a streak • Insights: your weekly trend, your best hour and your worst one • Live Activity on the Lock Screen and in the Dynamic Island • Home Screen and Lock Screen widgets • Quiet hours, call detection, walking detection, and a choice of cues WHAT YOU NEED AirPods with motion sensors — AirPods Pro (1st, 2nd or 3rd generation), AirPods (3rd or 4th generation) or AirPods Max — worn and connected, plus the Motion & Fitness permission. Without them Pillar still opens, but it cannot measure your posture. PRIVACY Head position is analysed on your iPhone. Raw motion data never leaves the device. There is no account, no camera, and no photo of you anywhere in the product. PILLAR PREMIUM Free: one posture session a day — with everything in it.
