Pro version contains no ads or nag screens, uninstall feature, custom tune feature, the ability to hand pick the applets you want, safety check for missing applets on start, and better overall support. The pro version will receive more frequent updates than the free version will.
This installer has the smallest Busybox binaries available, right around 700kb unlike the other installers which are over a meg. Also this installer does not require you to download anything extra like other installers do and thus works much faster.
Please note I did not write BusyBox! I wrote this installer, cross compiled BusyBox for Android. Please see the about menu option for more details or here: www.BusyBox.net
BusyBox is a software application that provides many standard Unix tools, much like the larger (but more capable) GNU Core Utilities. BusyBox is designed to be a small executable for use with the Linux kernel, which makes it ideal for use with embedded devices. It has been self-dubbed “The Swiss Army Knife of Embedded Linux”.
This version includes 1.20.0, 1.19.4, 1.19.3, 1.19.2, and 1.18.5 no need to have more than that because it takes up space on your phone and each newer version will still contain the older features, unless I forgot to compile them in.
Leave this installed if you always want to get the latest version of busybox!
