Great app, make greyscale easy to access. It so long hidden inside setting to officially turn on and off, this app make it very easy just turn on and off from the control center.

This is perfect! No root required, just connect to a pc with adb installed and give permission via copied command. Thanks!

Not the best choice. Needs root. Or PC to root or enable developer options comprising privacy and safety.
