CM Apps is an app that lets you install the exclusive CyanogenMod apps on your device. (No root required!)
Note: I did not make these apps. These apps are made by the CyanogenMod team. I only provided 'download links'.
This app is just made to install the CyanogenMod apps, but sometimes those apps don't work just because you don't have CyanogenMod. It's not my fault, those apps are just meant to be on the ROM itself.
