From the developer:
Memory Clean is an app for optimizing your Mac's memory and is best used after you have finished using a memory (RAM) intensive app or game. It replicates the feeling of a fresh system restart.
Memory Clean works by purging the Mac's inactive memory and is best used when you close an intensive program that you do not plan to use again quickly within a few hours.
