Does NOT get your PD value correct This app does NOT get your PD value correct ... I've tried multiple times, but it gave me the numbers from 61-63, which are incorrect! I know these values are incorrect because I went to an eye doctor which measured my values as 71! Absoloutly do NOT recommend this app, because when buying glasses you MUST have the PD value correct.
Please go back to the drawing board! I appreciate the idea of this app. Today is like pulling teeth to get these measurements from any establishment that sell glasses. Online companies have no overhead so is far more economical. This app could be a great success but falls way short on accuracy. 9 measurements all averaged compared to an actual measurement by the doctor was 7mm off. Needs a lot of work. I suggest pulling it off play store completely.
Don't download Don't use, it's was very difficult to get an accurate reading. . . .Very very fiddly
Terrible I can't place the marker because I can't see where I am placing it.
Works. Finally got it to work and when I went to get measured for new glasses they said it was right.Would have appreciated better directions.Didn't use a credit card just some points card for a store that no longer exists.Credit card seemed too iffy.
Works fine This confirmed a ruler measurement. Not sure about showing the back of the credit card....i.e. Showing the 3 digit pin off so used a nectar card. Make sure you hold the card straight and take the picture in landscape mode. Overall good app that works.
