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 4.8

We have added a preference option to disable the auto cooldown timer as per user feedback. Please kindly leave an updated review and we'll keep bringing you updates :)

Works Very Well !!

I started using this app after installing extra RAM memory on my iMac (from 8GB to 16GB). While running the ActivityMonitor utility, I noticed that the RAM memory was being used up and not ‘released’ after the applications were shut down. After researching this issue on the web, I came across a recommendation from a Mac magazine which said Memory Clean would do the job….and that it did! I was down to 70MB regularly, but MemoryClean released the dormant part and gave me over 6GB in just seconds. The ActivtyMonitor app confirmed that the memory was indeed free to use by another application. I run it regularly now, keep an eye on the top bar where it is constantly displayed. Highly recommend it. Very easy to install and run. and cant beat the cost, its free!

Works perfectly!

I love this app! It works perfectly! This app lets you clean your memory, making your mac so much faster! This app is also very useful because it tells you what is using up your memory and how much memory your mac has left. This app has a lot of useful features as well. You can make the app's status bar turn red if the free memory goes below a customizable amount. You can even make the app automatically clean your memory when it goes below a customizable amount! This app is great if you work with a lot of applications open simultaneously. It only takes seconds to clean gigabytes of your memory. The best part is that it is FREE and will never, never, never ask you to buy anything!!!! I strongly reccomend this app.

Highly Recommended

This app sits on the menu bar and shows you how much free memory is avaiable and turns RED when you are running low. If you multitask multiple applications with multiple documetns open simultaneously (like Mail, Safari, Word processer, Spreadsheet, Presentation, Preview), then try Memory Clean. Memory Clean will improve your productivity by eliminating PINWHEELS and allowing you to get your work done. You just click on the CLEAN MEMORY button and it takes care of the rest. I have recovered up to 7 GiGs of memory in one cleaning. Also, If you watch the Memory Clean display as you run more apps and open more documents, you can see which ones are the memory hogs.
