Knock Lock

Knock Lock


Pro version available here: https://play.google.com/store/apps/details?id=pl.damianpiwowarski.knocklock.pro - with floating Knock Lock!

This app alows you ONLY to lock device. Unlock feature is available in my other app - Knock Unlock (beta, may not work properly) (https://plus.google.com/communities/102983045850460117969)

Knock Lock is simple application that allows you to select area on your display to enable "knock to sleep" feature. Also in app you can select size of area available for knocking.

- How does it impact battery life?
App does nothing other than creating small area for knocking. Battery usage should be below 0.1%.

- How to uninstall this app?
Remove access to service that you have selected at start. You can do this by clicking button in app again and selecting "device admin" section or by going to Android settings -> security -> Device Admins. Then you can uninstall app.

-Why there is visible notification?
This notification is part of Android responsible for keeping app alive all time. You can hide it in Android app settings (there is option to hide app notifications from showing).

If you have problems with app or want to ask question, email me from this app page.

Recent changes:
- Added option to select any color for floating knock lock.

- Knock Lock (transparent, free version) now saves portrait and landscape position. You can select where knock area will be available for both orientations

Wherever you out the knock sensor it's a dead spot on the screen, you can't touch anything in the screen there (if you set it where your keyboard is it won't let you use some letters) other then that great app

Good app Make it so that you can have more than one hotspot and this app needs an option for blacklist of apps in which you can disable the knock lock

I love it and it works well This app needs more introduction and direction to it. I spent some time to figure out what this does. And maybe other features can be added into this "double-tap" feature, like opening an app by it. And I can't swipe down for notification drop down because of the double-tap active zone, maybe this could be fixed? Otherwise this app is perfect. Recommend downloading this app for a try!
