Good thing I didnt rely on this app!!!

If I could give this zero stars I would! The process seems logical, seeing that based on the relative width of a credit card a simple calculation could be made by the app to determine my pupillary distance. NOY THE CASE. After taking several photos, arms length and closer, my PD was 53.5. Called my optician, since they were closed the day I wanted to order lenses and bought this app as a result, and they said my PD was 61! This app was WAY off! I could understand and excuse 1-2mm, but 7.5mm difference?! Wish I had just waited and not wasted a dollar on this app!
