Awesome Feature of HALO!

Set a custom schedule for night mode. “Apply this function when using your personal device while lying down on bed.” Night mode will only activate at the scheduled time if you are using your device while lying down.

Execution Condition: Night mode activates only when the device is turned upside down (180°), to the right side (90°), or to the left side (270°). It will not engage night mode if you are walking around outside at that time.
