About this app

Screen Lock, is created to extend the life of the hardware power button by using the feature within the app. Support for both Admin lock and Smart lock system. Easy to Screen off and lock the device depending on your selected preferences.

This app uses the Device Administrator permission. Necessary for the app to lock with Admin lock. Read write system settings permission to enable the Smart lock feature if needed.

This app uses Accessibility service. It is optional for only Android 9 and above. Used only for taking advantage of the internal Screen Lock option to overcome the delay in the Smart lock feature.

One tap to off and lock the device using:
☞ Admin lock (Shortcut)
☞ Smart lock (Shortcut)
☞ Screen lock widget
☞ Admin lock and Smart lock from notification
☞ Floating widget

Screen lock using available device sensors for both lock and wakeup feature:
☞ Flip cover
☞ Air swipe
☞ Desk option
☞ Awesome shake

Usability enhancements:
☞ ‘Movement listener’ option for a distraction-free reading experience.
☞ ‘On home screen’ for easygoing.
☞ ‘Pause on landscape’ to play games effortlessly.
☞ ‘Pause on call’ to let the device follow its default course of action.

Personalisation features:
Animations to pick for Phone lock experience. Vibration feedback upon Phone locked. Lock and unlock sound at varied points to play the tone you love to hear. Sound volume is picked from notification sound as volume and can be further adjusted with ease, also respecting DND mode.

Highly customisable lock icon with an easy-to-use interface. Option to use Metallic and Material icon as a choice for both Admin lock and Smart lock.

Animation speed is adjusted with the “Transition animation scale," and “Animator duration scale”. Our advice, use 1x for the best ‘Screen Off’ experience. The changes may take place after lock and unlock.

Note 1: Device administration must be disabled before uninstalling.

Note 2: Disable default device lock and unlock sound, if applying from this app.

Any suggestions for improving the Screen Lock app are most welcome. We’ll do our best to present you desired usage experience.

Ratings and reviews

Not a bad app. Took me a while to get used to where it can be a little confusing. I still am not positive what difference is between two lock systems. Like that I don't have to use power button, but Reason I'll probably uninstall is that is is cutting my battery life down it's new phone and went from lasting 2 days to one. Without using. No I have not installed anything else since. Wish i could find an app with tap to unlock and wave.

Very convenient and helps to prolong the life of your lock screen button. Has an option where you can drag your screen down and lock it from there so that you can lock your screen while using any app. You can also create a shortcut on your home screen and simply click on it to lock your screen immediately. Been using this app for more than 5 years on 3 different phones and honestly have never had a problem with it. Can't imagine not using it

though this free version still works for my newest phone (Galaxy s25+, android 16), while the pro version (which I purchased and used successfully up till this phone) now just crashes whenever I try to use it, I'm still becoming concerned about security with this free version, since it hasn't been updated since 2024! please update or document assurance that you've thoroughly vetted this version for Android 16 and that it's still secure! I might have to uninstall otherwise. thanks .
