THIS APP IS DISCONTINUED SINCE 2014! If you install it, don't rate it 1 and say "Needs an update". Makes no sense. There's a free version in the link below.

For discussion, free version and source code: http://forum.xda-developers.com/showthread.php?t=1920057
Overview ZipInstaller is a tool that makes it easier and faster to pick up and install zip files through your recovery. Instead of manually rebooting into the recovery and selecting files from there, you can pick up all the zips you want with your favorite file manager from the sdcard and install them with just one click, that's it.
TWRP, 4EXT and CWM-based recoveries are fully supported. Closed source CWM is only supported through RomManager premium.
