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 is very well done. My lighting wasn't so good and I did have to use manual mode, but it allows you to really fine tune it. I'm going to trust the accuracy and went ahead and ordered. [Edit: Joke removed]
Is ok.
Dr said 64, This app said 63.5, so it's right on the mark if you follow the instructions carefully. If the credit card is on the same plane (even distance from camera) as with the eyes and not tilted, and camera straight on at arms length it works perfectly. Remember, if you tilt the card it will look and measure smaller and thus your PD will measure will be too large.
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.
Very useful, we just used our common sense!
Worthless... while I was using it for my own glasses' purchase, I thought I might also be able to use it in my math classes. Unfortunately, the variation in results make it useless for both purposes. I got readings of 48.7, 54.7 and 60.6; I used zoomed in pictures and was exacting in placing the green bar's endpoints. Very disappointing.
So complicated it isn't even worth downloading!
It would be nice if you could toggle a super slow movement of the alignment circles. Other than that it's fairly accurate if you set it right.
I measured myself with a ruler and then tried this app. I had to try a few times but the measurements from the ruler and app were only different by .9mm . I would say that this is fairly accurate. I'm glad i bought it.
