Turn Screen Off One Touch Lock is a free Android app developed by BitApps Games under the Utilities & Tools category. It is designed to enable users to turn off their phone screens and lock them with a single touch, without using the physical on/off button.

The app provides a digital button that appears on the desktop, allowing users to turn off and lock the screen with ease. This feature is especially useful for those whose phone's unblock/on/off button is broken, or for those who want to avoid damaging their phone's on/off button by using it repeatedly.

One of the main functions of the app is that it can automatically add a widget to the desktop to turn the screen on/off. Additionally, the app offers one-touch lock, which automatically blocks the screen when it turns off.

The app is also very useful for those who have damaged their phone's physical on/off button. With just one press of the button, users can turn off the screen quickly and easily, without having to press the on/off button excessively.
