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 5.4

New Feature: Memory Clean now displays apps using significant memory.

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. However, File Cache will still be cleaned by Memory Clean.


Message from the FIPLAB team: Memory Clean now has more than 5 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.

5 Star Quality, love the new "Apps using significant memory"

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.

INVALUABLE Mac Utility app

I have a Macbook pro (with retina) 16 gb and I use this computer for alot of gaming, and design projects (Adobe illustrator and photoshop.) Also, due to errors with the main game I play, ESO (Elder Scrolls Online), the system files caches builds up extremely fast….SLOWING DOWN my computer. With Memory clean it worked great! Normally I’d have to reboot after about an hour of playing, but with clean (and now running with Extreme Clean) my file cache goes from 5.65GB to 167mb!!! That’s insane! It’s now part of my daily usage. I would recommend to everyone! Especially new Mac users and other Mac users playing ESO. Untill the patches come out to fix the huge file cache issue on Mac this app is Essential!

Awesome update!

Love love LOVE the “apps using significant memory” update. Keep up the fantastic work y’all!

And if you don’t have the “deep clean” upgrade…do it. It’ll save your life.

Well. Probably won’t save your life, but it’ll sure make it a whole lot better, especially if you like to run 3 different web browsers simultaneously, plus Illustrator, plus iTunes, plus your email client, plus….you get the idea.
