I swear this is the only real app in utilities that I can, not only see thru visual graphs, but get something back, a stable IPAD3 and IPHONE5 ( although they are same power as far as chip and memory, I usually dont leave this app on in the phones background like I do in the Ipad3).
Once in a while I turn off all apps and start fresh like a lot of us do, as we use apps and mem up its not on our mind, then you goto run a vid or something and it just wont run right, or crashes over and over, the mem app fixes it everytime, Id rather have it off, and to be able to see it "clean up" then it do it on its own, which it does if left on in background, what most people would want I guess, especially those with less "motor" under the hood like an IPhone 4S or lower, whose memory is half of the "5".
This is the only app that I have gifted to multiple good friends and decent family (lol), that in itself should tell you, If I think its worth buying 6-7 times, for wife and fathers and friends, its a decent app.
I have used this app for a few platforms of Iphones, and I can attest to it working "for me anyway" on those other iterations of Apple devices. I also rarely review apps, since the original iphones debut, well minus one week, (remember they were more money back then, I think over $600 cash plus my contract) I might have done 5, thats less then one a year, and I have accrued 100s, so many apps most are turned off at this point, not this one, its a mainstay and although I always am on the lookout, on the market for apps that keep things running as good or better even, for these types of apps, this one still seems to be the best one at it, such a simple script, shut off all memory not being used, or essential to what the user needs right at that time.
Elegant technology, something tells me Mr. Jobs woulda liked to had this running in the background a couple times onstage, he also would have liked the simplistic aspect, no user input, just effect, an app that now opens, a webpage you were trying to view, the speed your accustomed to being brought back to life.
So in closing Ill give it 5 stars, and I dont like to rate products in that way, it seems everything in life except maybe some Ferrari supercar, or a Fountain jet boat could be improved on, but if I could afford either of those mentioned above, Id prolly give them 5 stars too.
