Yangguan

Yangguan is a local-first posture guard and slouch reminder app. Choose iPhone angle, motion-enabled AirPods, or the desk camera, set a guard duration, reminder pace, and ambient sound, then start. During a session, view live angle and reminder status; afterward review the result, reports, and achievements. The Desk Camera Guard detects slouching and head tilt. If you enable “Show a small window when switching apps,” Picture in Picture shows the last captured frame and a paused status when you switch apps or lock the device. Camera capture, analysis, reminders, and effective timing pause, and a local notification reminds you to return. The session continues only after you return to Yangguan and a fresh frame arrives. Camera frames are processed live in memory only. They are not saved, uploaded, or used for identity recognition. The free version includes basic guarding, standard reminders, in-app posture challenges, away reminders, and focus blocking. Pro adds unlimited sessions, longer guard durations, 30-day trends, full report search, and advanced reminder settings. Actual monthly, annual, and lifetime prices are shown on the App Store purchase confirmation sheet. Posture angles, guard history, and reports are primarily stored on your device. On supported systems, you may authorize Yangguan to write an intentionally started session to the Health app. Yangguan does not read historical health data, estimate calories, or upload health data to the developer. It does not provide medical diagnosis, treatment, or emergency medical services.
