Free memory (was Boost & Memory) is an app to monitor memory and disk space usage and clean up your memory. It increases your Mac’s performance by cleaning cached memory, making more memory available for new apps. The application monitors RAM usage on your computer and frees up unused memory with one click. With Memory Cleaner, you can easily manage memory usage. An animated status icon in the menu bar shows you the percentage of memory being used, as well as memory cleaning being run.
