It works ok on my 3GS but anything older it uses all the memory. Could be cleaner but it's worth buyin but I keep hearin proswitcher so I might try it out (Posted on 1/21/10)

So I started with Multifl0w because I wanted something prettier than Kirake that I had been using for a while. After crashing quite a few times, MultiFl0w works. I was only using the trial to see how it works and it works fine. But I remembered another app that I had seen previously called Proswitcher that did the same thing. Well i went and installed that, and I must say, you should be using that instead of Multifl0w. You get more options on how to activate, and the whole experience is much smoother. Acts more like cards on the Pre which is what both apps are modeld after. Bottom line, go get proswitcher, google it and add the source to rock today! (Posted on 1/10/10)

Switchpro is free and 10 times better. I'm going to donate to the Switchpro developer. (Posted on 1/7/10)

1.3 fixed the memory leak. Then 1.3.1 brought it back. Wish I hadn't updated because I don't notice any other differences. Please fix it again! I don't want to use Kirikae AGAIN! (Posted on 1/3/10)

Not as good as ProSwitcher (Posted on 12/28/09)

A genious app I love the rock and it's apps (Posted on 12/25/09)

Although the UI if this app seems to be nicer, it crashes everytime I tried to use it. Kirkae is a solid performer and free. This app never worked on my 3gs so why would anyone spend 4.99 when they can get a better app for free. Glad that rock allows free trials (Posted on 12/20/09)

This is what I've been waiting for, great app. (Posted on 12/19/09)
