This sounds a lot like
$1 for IOS. It just released recently, so I haven't yet quite found a use for it. But...it feels like it should be more useful than it is, if that makes any sense? I think it's one of those apps that I don't have a use for right now, just because it's knew. Once I'm used to having the app in my life, and remember I could use it, it could well be something I can't live without in a year or two.
