VisionGuard

With the latest machine learning technology, this app can protect your eyes from the desktop in just three easy steps:

1. Set the learning time
2. Place the phone on your desktop and place it directly opposite you.
3. Follow the prompts and keep the correct posture for 3 seconds. The app will remember your correct posture position.

As long as your head is below your correct posture range, the app will prompt you with a sound. You can also set the sensitivity of the test by double-clicking on the screen during the test. The app provides three sensitivity (sensitive, normal, and tolerant) to suit different people's learning habits. Show More
