Research suggests most people who work at a computer get neck pain every year — as high as 63% in some studies (Physical Therapy, 2018). The cause is usually silent: as you lean into a screen all day, your head drifts forward millimeter by millimeter. Your head weighs about 5 kg upright; tilt it forward to 60° to read your phone and your neck starts carrying a load of roughly 27 kg (Hansraj, 2014). Orvyn flips that story — a quiet posture coach that lives in the AirPods you already wear. SIT TALL. STAND TALL. WORK TALL. No posture brace, no smartwatch, no camera. Calibrate your upright once, and Orvyn reads your AirPods' motion sensors to catch the moment your head drifts forward. The cue never buzzes your phone — it arrives where only you can hear it. You just sit tall again. HOW IT WORKS 1. Pop in your AirPods and calibrate your upright baseline once — about 30 seconds. 2. Orvyn quietly tracks your head angle; its rebuilt engine reacts in roughly 2 seconds, and the moment you drift forward a cue brings you back up. NEW: SIT / STAND DETECTION Desk workers sit around 10 hours a day (BMC Public Health, 2020). Orvyn surfaces those hours: your sitting time, your longest unbroken sit, and your sit-versus-stand split — and when you have sat too long, it invites you to get up and stand tall. WORK ASSISTANT A focus clock that guards your neck. Work in posture-guarded rounds with short breaks and follow the countdown in the Dynamic Island. Drift forward mid-round and Orvyn tells you — quietly. LIVE NECK LOAD See the load your forward head angle puts on your neck, live in kilograms (Hansraj model) — plus a week measured honestly, real readings only, never padded.
