When to use my goggles today and of course they were dead. And then I remembered that the litchi app was free. So I downloaded it on my phone. I like the fact that the phone fits right in the controller. I find it easier to use the litchi app on my phone than on my ipad. I don't think I'll stop using my goggles, but it's nice to know there's an app you can load on your phone thats a pretty good match.
