Installing a custom recovery is a great idea if you want to install a custom ROM on your Samsung Galaxy S3 device. Generally speaking, you need to install a custom recovery if you want to install a custom ROM; however, that isn’t always the case. It is possible to install CyanogenMod on your device and it comes with the CyanogenMod installer. That same CyanogenMod installer will also install CWM recovery on your device. You will get directed to installing a custom recovery during most guides with rooting and installing custom ROMs. Although, a custom recovery like TWRP recovery is also useful for people who just want to use a better backup feature (NANDroid backups).

The Team Win Recovery Project (TWRP) is similar to ClockworkMod recovery but comes with a touch-based recovery environment. That means you don’t use the Power and Volume keys like you would with ClockworkMod recovery. Instead, you have the buttons on the devices display as you would expect to find on a modern smartphone feature. Apart from that, there isn’t much difference — both TWRP and CWM recovery have the same features as each other.
