Cyanogen Boot Animation Dark is a custom boot animation for the CyanogenMod theme engine. This animation has been tested and confirmed to work on both the CM 11 and CM 12 theme engine, although it is designed for CM 11.

In addition to the dark version, a light version with a white background is also available. The animation is 1080p, but it will scale down and run smoothly on most smaller devices.

If you encounter any issues, Kiernan Moore, the developer of this free app, recommends contacting him for assistance. It is recommended to create a quick recovery backup of your phone before installing the app, especially on older devices, as it requires root access.

Overall, Cyanogen Boot Animation Dark is an excellent option for those who want to customize their CyanogenMod device with a sleek and professional-looking boot animation.
