If you have ever flashed CyanogenMod to your device then you know that you must also flash the G-apps package or you will be totally without Google services. The reason Cyanogen can't just package Google Apps into their rom is because they don't have the proper licensing. Instead of getting proper licensing for G-apps in their corporate operating system, CyanogenOS, they decided to just build their own suite of apps called C-Apps.
C-Apps can be found in CyanogenOS, but now you can also install them on CyanogenMod. List of apps in the C-Apps package include Theme Chooser, Theme Store, Cyanogen Gallery, Cyanogen Dialer, and more! Head to the link below to download the C-Apps package.
