Posture Reminder

Features
Read full description

Your neck hurts because you sit still for hours โ€” not because you don't know what to do about it. Knowing isn't the problem. Remembering is. Fix Posture builds a daily routine of 15 physiotherapy-grade neck, shoulder and upper-back movements, and spreads it across your own desk hours. Eight reminders a day by default, roughly one every 75 minutes. Tap a reminder and the movement starts. An illustrated character performs it while a soft tone marks every second of the hold, so you can close your eyes and follow the sound. Nothing to read, nothing to work out. Tell it where it hurts, when you're at a desk, and how many reps you want. Tomorrow's routine is different from today's. Rest days don't break your streak, and a calendar shows every month you've built. Everything stays on your phone. No account, no sign-up, no tracking, and it works offline. FREE 3 movements and one reminder a day. FIX POSTURE PRO All 15 movements, the full eight-a-day schedule, and your complete history. Weekly or yearly, with a 7-day free trial. Cancel any time. โ€” Apple Terms of Use apply: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ https://mosoajans.com/terms-of-use.html https://mosoajans.com/privacy-policy.html

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 โ€ข Live posture check โ€” the front camera reads your sitting posture on the device, frame by frame. โ€ข A nudge, not a scolding โ€” a soft alert when you slouch, and silence when you're fine. โ€ข Privacy screen โ€” cover the camera preview so you're not staring at your own face all day. โ€ข Break reminders โ€” sitting still for hours is its own problem, so back-up tells you to stand up. โ€ข Your day in numbers โ€” 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, with at least 30 minutes between app open ads. 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.
