KnockOn – Tap to wake or lock app


With KnockOn you can easily wake or lock your phone with a simple double tap on screen!

The double tap to wake and double tap to sleep feature can be used seperately.

You can also use the homescreen widget to turn screen off if you like!

• NEW: Fingerprint sensor compatibility (For android marshmallow)
• Double tap to lock your phone
• Double tap to sleep
• Double tap to wake your phone (OLED displays only!)
• Both features can be activated separately
• Set up a sleep time to reduce power consumption
• Customize double tap speed
• Triple tap option
• Homescreen widget to turn screen off

Remove device admin rights first or click “uninstall” in the app settings

If you use the double tap to wake feature the app will display a black screen, so the screen is actually on.
The battery consumption may be higher when activated! Do not use with LCD screens, OLED only!!
On Marshmallow Google disabled locking screen if you use fingerprint unlock. Just activate fingerprint mode and use double tap to sleep without problems.
