Most posture trackers ask you to wear or stick another device on your body. Posture Nudge works with supported AirPods you may already be wearing. After a quick calibration, it uses their motion sensors to notice when your head stays tilted down and gives you a gentle reminder to look up. No chest clip, no back sensor, and no extra hardware to charge. I built it for my own coding sessions, and I’m launching it now to learn from real users.
