Big, if true

When my programs are loading slowly, and my computer is chugging, I open activity monitor to see what problems there may be. However, the activity monitory says everything is fine - nothing is under pressure and there is plenty memory. I'm not sure why it says that when it's chugging, but when I have this little app running, clicking optimize once in a while gives a noticable kick to my system. The kick may be short, but it's enough time to actually kill the problem that's too busy chugging to allow me to kill it. Great app!

Just the perfect blend!

Tried several Memory Cleaners and hated the idea, and despite knowing that they are not generally required, I sometime find myself needing to flush things out, speically cached apps memory, this little thing does the job and does it "Reall Quick" it doesn't take forever to fill my whole ram with garbage before it cleans it, its fast, efficient and unobtrusive, No Ads, No In-App purchases, straight to the point utility that I cannot live without!

Improves performance substantially

Before using Memory Cleaner, I was getting the spinning color wheel all the time with 5-10 web pages open (Safari and FireFox) in the dock as well as 10 open emails in the dock. There seemed to be a lot of VM swapping in my 8Gb iMac. Now, the iMac is more responsive with almost no thrashing. Also, seeing the amount of memory available makes for less sloppy habits with open apps.
