Works great. Got one number for 3 tries, then got a slightly higher number (1 mm higher) the 4th time after looking into the distance when taking the photos. Need to go read the directions again to see if I did it exactly right. Will update shortly.... UPDATE:. I didn't see instructions on how far to stare when taking the photo. So when looking at the camera, I got 66. When looking into the distance, I got 67. Seems pretty accurate to me. SECOND UPDATE: Thank you, GlassifyMe!!

The app in fact takes into account for your distance PD when you are looking into the camera. Thank you for the review!

It works decently. I got 67mm using a ruler in the mirror and this gave 67mm. The only way that I could get a good result though was by using a tripod with a phone holder attachment. Would probably work better with a friend taking the picture for you also. I would like to suggest to the developers to put the shutter buttons higher up on the screen, because that's what made it hard for me to use. It's awkward to hold the phone down low so you can reach the shutter button with your thumb.

Fairly accurate, but can be difficult in selfie mode. Luckily, able to use a friend and rear camera to make a bit easier. Since the selfie flips for alignment, can be harder to get the card straight and flat on subsequent tries. Kind of important since the card is used for the basis of the measurements. Getting the card straight and flat in the picture, as well as keeping your eyes open as wide as possible (think old Dracula movies) will improve accuracy since you control the outcome.
