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.

About

Posture Reminder

Read full description

Set your phone on your desk. back-up watches how you sit and gives you a gentle nudge the moment your back starts to curve. No account or app backend. No video ever leaves your phone. WHAT IT DOES • Live posture check — the front camera reads your sitting posture on the device, frame by frame. • A nudge, not a scolding — a soft alert when you slouch, and silence when you're fine. • Privacy screen — cover the camera preview so you're not staring at your own face all day. • Break reminders — sitting still for hours is its own problem, so back-up tells you to stand up. • Your day in numbers — today's summary, the last 7 days, and the hours when your posture usually falls apart. BUILT FOR PEOPLE WHO SIT ALL DAY Students, desk workers, anyone whose lower back has opinions by 4 p.m. back-up is made to be switched on and forgotten. PRIVACY, PLAINLY Every camera frame is processed on the device and thrown away. Posture history also stays on the device. If app usage analytics or crash and error reports are enabled in Settings, app-usage or diagnostic information that is not linked to an app account is sent to Google Firebase; it never includes camera video or posture history. For returning users, Google may show an app open ad at launch or on an eligible return to the Statistics or Settings screen. Each launch after the app is fully closed attempts an ad; background returns require at least 30 minutes since the last app open ad. A small banner remains above the bottom navigation on the main screens. Clear your posture history any time in Settings. App languages: English, Korean, Japanese, Simplified Chinese, Traditional Chinese, Spanish, French, German, Brazilian Portuguese, Italian, Russian, Arabic, Hindi, Indonesian, Thai, Vietnamese, and Turkish.

Verdict

The call

The clearest difference is in-app purchases: Posture Reminder at none against Noodle's 6. Posture Reminder also leads on device support (3 vs 1) and iOS requirement (15.1 vs 26.4). Noodle's advantage is ads (none vs shown) and update cadence (every 5 days vs every 2 weeks). On price there is nothing between them.
