The app is designed to run on the CyanogenMod them engine and includes only the Nexus Pie boot animation. The animation is 1080p and runs smoothly on most smaller devices. The app has been tested to work on both the CM 11 and 12 theme engine, but in CM 12, it still says designed for CM 11. The developer recommends taking a quick recovery backup of your phone prior to installing the app, especially on older phones, as the app requires root. If you face any issues while using the app, you can contact the developer.
