FEATURES: • Tracks torso orientation using the iPhone’s built-in motion sensors • Shows time spent side-sleeping vs. back-sleeping • Provides a nightly sleep posture summary • Optionally integrates with Apple Health, with your permission, to help you view sleep and recovery metrics alongside posture patterns • Stores sleep posture data locally on your device IMPORTANT DISCLAIMER: NightPosture is for general fitness and wellness purposes only.
