Ratings and reviews

It sucks got too many different numbers over and over and over. I had not played for it and I wished I had not paid for it don't buy it this is horrible.

This app works pretty well but you have to spend some time and follow the instructions. Once I made sure the reference card was in the same plane as my eyes and the camera was arm's length away (so that it doesn't distort as much) I started getting results within 1.5mm of each other. I took several shots, averaged them, and came up with a useful number. Took about 15 minutes to get it right. Galaxy S7 with the back camera so I could use flash.

First I will say that I do infact have access to an optometrist grade pupilometer and so I have something to compare this to, and it was extremely accurate when measuring the rest of my family, however got mine quite a bit off which I will now explain what I believe to have hade the difference. The difference is truly in getting the correct alignment of the card and the position of the eyes. When attempting to measure my own PD I was using the front camera and looking at the phone trying to see and press the shutter button, and trying to align the card by feel, whereas when measuring my family members, I was able to see the card and eyes and get proper alignment and also they were looking straight ahead instead of at the phone screen. Overall I would say the concept and accuracy of the app are spot on with proper alignment, but looking straight ahead your eyes will be positioned slightly different for focus than if you are focused on the phone screen and the alignment and size of the reference card matters, for best results have somone give you a hand with card alignment and taking the picture and you will get an accurate reading. I definitely agree that an app like this was worth it as most eye professionals will typically refuse to give you a reading unless you are ordering glasses directly from them, and even then they are hesitant to give you the numbers, hence the reason I spent the money getting my hands on a pupilometer on amazon in the first place.
