About

Posture Hero

Get Posture Hero to start building better smartphone posture habits today. No equipment required. Digital wellbeing apps measure screen time. We're the first to measure screen posture. Prolonged mobile-phone use is linked to more than double the risk of neck pain, a condition already impacting 222 million people worldwide. Posture Hero closes that gap: it detects sustained low viewing angles in real time and nudges you back. A notification reminder appears the moment your neck drops into a strain zone. It runs quietly in the background, with no camera, no wearable, no extra hardware. It's just simple tilt detection that respects battery and privacy. Sensitivity, timing, and sound can be personalized on the pro plan but the app works 100% on the free plan. Progress analytics turns everyday phone use into healthier, lasting posture habits. Screen time apps tell you how long you were on your phone. Posture Hero tells you how you were holding it and helps you fix that before chronic pain. Tilt Detection Uses your device's built-in sensors to detect slouching without any wearables. Smart Alerts Gentle, non-intrusive reminders appear right on screen when your posture dips. Progress Streaks Track how long you hold good posture each day and build lasting habits.
