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 :)
Worthless Better to jus go in to any eyeglass store to get the right number. This was off by 15 to 20 every time. To late for the first pair of glasses I order trusting this worthless app.
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
Accurate enough I have my own PD from the optometrist (near, inter, distance) but wanted to check my wife's PD. I have 64, and this app got me 64.5mm - but the photo and alignment of the card do have to be good.
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.
