Meh!

While it does what it is says it will do 80-90% of the time. The app is unstable, self closes when I am trying to scan a card in, black screens until I kill the app or just seems to freeze at times. Of 5 cards yesterday, I had to almost completely redo 1 and fix minor errors on 3 more. 1 card went in flawless.
