Back when the Android was young, AndroZip was the compression software. Today, other software can also unzip files e.g. Astro file manager. So what do you do? You offer better features! And that’s what AndroZip did. It can compress and uncompress 8 different formats including RAR and 7z. It also offers encryption with ZIP files. The interface is easy to use and there is no need to hunt for the action buttons. I personally do not have much use for a compression software but I still have it installed. Its like an anti-virus app; you don’t know how much you need it until you need it!
