A free program for Android, by JRummy Apps.

This free app is a utility that can tell you if your device is rooted or not. It’s made for Android devices that have root access and are running a custom ROM. It does not modify any system files and it is completely free.

If you have root access, the app will give you information about the current state of the device (rooted or not). It will also tell you if the current version of the OS is based on a custom ROM.

In addition, the app has a beautiful design that will let you know at a glance whether or not your device is rooted.
