Accurate if you know how I tried about 6-7 times and knew the results weren't correct because the card wasn't parallel to the camera or my head wasn't. I finally decided to stick the card to my forehead, so at least if my head was good everything else would be. The next hurdle was that I was trying to align the green outline of the digital card to my card and that always yielded slightly off results. Just focus on putting the center marks on the outside radius and it will be golden. PD was verified by OD later :)
Don't pay for this Used it when brought it this afternoon then when I went back into it, it wouldn't open. Waste of time and money
Says it's not licensed - can't use It's like a refund please as I can't use this. I tried uninstalling and reinstalling.
It Works Great little app. Does exactly what it's supposed to.
The directions just state that you need a reference card but doesnt state that the card should be a credit, gift card or similar. It needs to be more specific about what a "reference card" is.
Very accurate application !
