BusyBox is a collection of powerful command-line tools in a single binary executable that can be run for UNIX based systems, including Android. So in short busybox hmmm.... Allows more Linux commands!
Some apps require busybox to be installed. To install busybox just root your phone then go to the Play Store and install busybox installer and let it install.
If your phone isn't rooted and you don't want to root your phone then ask the developer for a money refund.
