Memory Clean is the ultimate app for optimizing your Mac's memory and is best used after you have finished using a memory (RAM) intensive app or game.

With the slickest interface and user experience, Memory Clean stands head and shoulders above the rest.

Note: Memory Clean works by purging the Mac's inactive memory and is best used when you close an intensive app that you do not plan to use again quickly within a few hours. During the cleaning process, older Macs may slow down until the cleaning is complete.

More free memory but more swap and slower system...


I could maybe live with the annoying ads for other products, if this app actually worked, and, in that case, might have rated it a 3 or a 4. But this app made my system slower than it has ever been. I rebooted and then ran a memory-intensive app, then I watched the built-in OS X activity monitor while this app was running… free memory went way down to almost nothing, while it was doing its "clean". When it was done, which took quite a long time, the activity monitor showed the same as this app and most of the previously inactive memory was now free. This all sounds great and I was happy that i could now change most of the inactive memory to free memory anytime that I wanted to. I noticed that my computer was experiencing an unusual amount of disk activity and everything had slowed to a crawl. A look at activity monitor again told me that swap used, which is almost always 0 on my 16G system, was now 2G, even though free memory was now over 10G. I shut down and rebooted my system and all was well again with one other anomaly… this is the very first time that I've ever seen recovered files in the trash, after a reboot. Another ill-effect of running this software. I have now removed this app and hidden it in my purchases, would rate it negative 5 stars, if that were possible.

Easy to use and super efficient for FREE


So I’m currently a senior in college and I got a macbook pro when I was a freshman. When I purchased my macbook I got memory clean on the app store since it was free and was skeptical on how good it was and how it would help my computer run and I must say it’s done a great job for the past 4 years on keeping my computers space free and notifying me when its low. I especially like that you can get the GB storage on the top navigation bar on your computer it makes it much more hepful to use along with keeping me aware of my free space without having to dig through a bunch of apps to find it.

Just what I needed when working a project with A ZILLION files open!

Believe Big

I highly recommend this easy to use cleaner. This APP has saved me when working a major projects with so many pages and picture/graphic files open. Usually my computer slows and/or even stops my work—very frustrating! Thankfully, I found this Memory Cleaner APP. It is so user friendly and works quickly, so I may move onto my more important work! Thank you to the developers who continue to provide support through updates that fix little bugs and continues to make this my go-to cleaner option!
