ClockworkMod recovery  is currently the most popular and extensive custom recovery tool for Android devices. The default Android recovery that comes with most Android devices is a bit basic in functionality and doesn’t offer many features that ClockworkMod serves a user with. Advanced backup and restore tools, USB mounting, SD card partitioning, ability to install or update both stock and custom ROMs, and so on are only some of the features that make ClockworkMod important for any Android user.
ClockworkMod Recovery Touch gives you the ability to utilize your device’s touchscreen interface (as well as the physical buttons), while the usual ClockworkMod recovery uses only the physical buttons on Android devices (Volume up, Volume down, Back, etc).
