Do you ever find it difficult to reach certain buttons on your smartphone's large screen? This app, called "One-Handed Pointer," allows you to click buttons that are out of reach with just one hand. Similar to a touchpad on a laptop, you can move the pointer and click buttons, enabling one-handed operation. Even when using other apps, you can still access the pointer as long as the app is running.

To minimize battery usage, the app has minimal features and does not require network communication. The basic functionality is available for free, while additional features such as changing the color and transparency of the launch area, automatic app startup on phone reboot, and pointer speed adjustment can be unlocked with a paid license for $2.99.

The app allows you to virtually click buttons and links that are difficult to reach, making it easier to operate your smartphone with just one hand. The pointer moves further when swiped quickly and gradually when swiped slowly. When in full-screen mode, the launch area becomes hidden. You can also pause the app from the status bar notification.

To set up the app, enable the "One-Handed Pointer" option in the accessibility settings. For Android 6.0 and above, you will also need to grant the app permission to appear above other apps.

Overall, "One-Handed Pointer" is a useful utility app for those who struggle with reaching certain buttons on their smartphones. With its simple interface and convenient features, it makes one-handed operation much easier.
