Installed very easily. Works great. Cleared up a lot of RAM memory for me. My Mac frequently locks up because I use several memory intensive applications. This app cleans up the memory and gets me going again. It does launch and works very well. When it launches, it puts an icon in the menu bar. Click on the memory chip icon and you can see your available memory and defrag if necessary. It doesn't get any simpler than this!

This low-cost app does its job. It's simple and works. I use several memory-intensive applications and this cleans out RAM with one click effectively. It gives my 3 year-old processor a little more time to live and it sends the developer grateful thanks.As to the other comments in this thread, I have to state that the app name 'Memory Defrag' is totally accurate; if I wanted a disk / hard-drive defray utility, I would have search for the latter! The app could not be easier to install - it sits with a small chip icon on the top app bar. As for user-friendliness, there's only one button to push for heaven's sake! For $0.99 it works as advertised. Thanks for an ethical price and a utility I needed. 4 stars - because as a developer, I know you can always do better :-)

The app is in the top menu bar (next to battery and wifi indicators). Simple to use and seems to work alright.

Poorly designed app and not user friendly. I am still unable to open/ operate the app even after reviewing the developer's recommended information on the macro status bar. If the developer is aware that customers are experiencing issues with opening/ using their app they should attempt to address these ssues and improve the app's functionality. Don't waste your money on this!!!!
