Seems a little suspect, released on July 7th, free on the 17th ... but here's a heads-up for anyone that might need it anyway. Grabbing it now to check out. App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
I just tried DocScanner Pro out and it worked okay. CamScanner is sitting at $4.99 and I put it on my watch list ... if you've tried DocScanner Pro, I'd be interested to hear how the features/functions differ. I don't need a scanning app all that often but still not a bad idea to have one just in case I suppose.
