There is a whole lot of things flashing across the screen when you turn this thing on and it and then you hit the optimizer and it says your phone is optimized. Well I've got another apps that do the same thing after I run it through here I turn them on and there's nothing to do it's already done so it does work and it's all in one app you don't need several of them to do what they doing what happened. What I hate though is you have to updated every time you use it. that takes about 5 seconds but it's still annoying and I don't know why I got to update it every time you use it. But I gave it a thumbs-up it works and I have proof that it works so I've deleted my other apps
