While I'm unaware of a way to determine stats on downloads or revenue... you can use App Annie (http://www.appannie.com/cloth/ http://www.appannie.com/cloth/) to get a reasonable idea of how the app is doing. From App Annie: They've been featured roughly ~110 times on the app store in various more prominent areas. And their ranks look semi-decent. My 2 cents: He's at least made his money back and probably a little extra on top.
