AWARDED MACWORLD 'MAC GEM' 2013 - The Best Memory Cleaning App

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.

What's New in Version 5.8

This update adds the ability to hide the 'Unlock Extreme' button on the user interface. Thanks for your feedback - we do listen. Be sure to check out our new free alarm clock app, search for 'Timeless' on the Mac App Store.

We hope you are enjoying the free themes we added in the last update! Please email us with suggestions for more theme colours and new features :)


Message to OS X 10.10.3+ Users - Please note that Apple has updated the way Used Memory is calculated and that's why we no longer include 'File Cache' in Total Used Memory figure. If you compare with Activity Monitor, you will see that the Used Memory figure in Memory Clean matches up with what is reported on Activity Monitor. File Cache will STILL be cleaned by Memory Clean.


Memory Clean now has more than 4 Million downloads! We'd like to thank all our loyal users for supporting us for nearly 4 years! Memory Clean has won multiple awards during that time, including the MacWorld 'Mac Gem' and 'Invaluable Utility App' from Apple.

Please kindly help support the development of Memory Clean by leaving us an updated review!

No need to hide “Unlock Extreme"

// You guys have all the right to place the Unlock Extreme front and center and anyone who is using this app should be fully content with it being there. You have an excellent product and people are getting plenty already for free. You need to make money to keep building great software, so offering a higher tier is an easy way to keep supporting your great work. Keep it up and don’t worry if people complain about you advertising your paid products.

This app was a blessing for my 8GB RAM Macbook Pro from 2010. She needed a little help, and this app is the one to give it. It handles memory better than the built-in modules by doing a deeper clean. Since I’m a power user and have a lot of heavy apps open at once, this is invaluable.

Casual users have no need for this, but if you’re a power user, this is the memory app to get.

I just upgraded to a Retina MBP 15” from 2012 with 16GB RAM and still use this and haven’t had a stall since. It’s even better on new machines, though I haven’t tested running the machine on full without this app turned on and managing my ram. We’ll see, but I’m more than happy leaving it on.

Makes my 2008 computer far more usable

This program went from good to great a while ago. I tried playing a modern game and my poor 2008 imac would get absolutely hammered on and cry to its mommy. Even with an older version of memory clean I’d launch it then the performance would get really dodgy. Now it works quite well (still in quite low graphics settings but hey it’s a 7 year old computer!) I just bought the extreme clean upgrade just because I’m so pleased with the app. I don’t even really care if that helps, just want to give the devs more money. Thanks!

Nice App, Bad Ads

I paid for the “extreme” version of this utility and am very happy with it. Most of the other reviews which compliment this app state my high opinion of it, so there is no need for me to repeat what they say. I do not, however, appreciate the shilling for other products every time I open the (paid for) “extreme” version of the app. If I were using the free version, I would have no problem with that, but as a paid-up customer, I do not appreciate having to navigate FIPLAB’s ads before I use the product each and every time.
