Superuser - Root Checker is a free utility application developed by Yves Apps for Android devices. This app grants and manages Superuser rights for your phone, but it requires that you already have root access or a custom recovery image to work.

It's important to note that the app and binary will have different versions, as the app is updated more frequently than the binary. Additionally, if the app was installed with your ROM or root, it cannot be uninstalled. If there is no uninstall option, it's because you placed it in /system/app, not the developer.

Overall, Superuser - Root Checker is a useful tool for managing Superuser rights on your Android device. However, it's important to ensure that you have the necessary prerequisites before using this app.
