Ratings and reviews

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.

Incorrect measurements despite several attempts. Went to a eye doctor for a proper measurement and this app was about 10mm off.. Waste of $8. Also a pain to use when you can't see the app. (While the setup boxes are bright, they are super thin, so when you have to take your glasses off for measurement, you aren't able to easily make out where to line up your head.. maybe make that a little bolder.

It worked well. I wish it had 2 features. I wish you could rotate the lines while measuring the card width, in case you hold it a little askew. It probably doesn't make much difference, but it would increase my confidence in the result. Also, I wish you could zoom in while correcting the pupil detection. It was a little hard to see my pupils. Finally, I appreciate the privacy warning, but it should be more explicit. Do not use an unmasked credit card, even though I believe they are honest.
