Noodle helps you catch slouching sooner and build a better sitting habit one reset at a time. Start a Slouch Watch, sit tall once to calibrate, and Noodle uses supported AirPods or Beats head-motion data to watch for forward hunching while you work, study, scroll, game, or take calls. When you start curling toward the screen, Noodle gives you a gentle cue to sit upright again. Want to try it first? Slouch Test Drive lets you sit tall, slouch on purpose, and watch Noodle catch the hunch before you subscribe. Trends shows how your posture habit is growing with live reads, manual check-ins, upright minutes, streaks, best days, and weekly or monthly scores. Your Noodle levels up too: earn ranks, unlock hats, held items, backgrounds, and shareable Noodle cards as you keep showing up. Features include: Live slouch and hunch detection with supported AirPods or Beats Gentle alerts, optional sounds, and background notifications Lock Screen and Dynamic Island Live Activities See today's posture at a glance with a home screen widget Slouch Test Drive, Trends, check-ins, streaks, and ranks Unlockable hats, items, backgrounds, and share cards Adjustable detection and movement sensitivity Motion processing on device Noodle is for everyday moments when your neck, back, and shoulders start drifting toward the screen.
