Tells me recurrently I have 1 GB more free memory than what Activity Monitor’s memory pressure shows. The best feature is freeing up memory of course, which seems to work well.

I’ve been using Memory cleaner for a couple of years: so simple and efficient. Despite the insane invader, Nektony’s brave team is still on deck, and offers quick and enlightened support, even for free users: hats off to you Nektony!

Have used a few different memory apps and this one is by far the best. Menu bar icon works really well and being able to see a full list of all applications using memory in order of the biggest hogs to the least is helpful.

With Memory Cleaner, you can easily manage your 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.

I am very impressed with this app. It is made by Nektony which also makes App Uninstaller, an app that I have used for several years.
