## Pupil Distance PD Express Reviews in United States

### ****- "Great to have"
As the online optical industry grows, its great to have an accurate way to measure PD. No more guesswork. Thank you.
-- Cmchuck, 2024-08-13

### ***** "My Screen is Black"
Help! I have been using your app for a few years and it recently started displaying a black screen.  I have uninstalled and reinstalled it several times, this seemed to have temporarily fixed the issue. It has since reverted to permanently showing a black screen when I open the app. I tried to contact you through your tech support feature, to no avail. 
Thanks!
-- seventrumpets, 2024-06-14

### *---- "Not accurate"
Not accurate
-- Jcraig1800, 2022-04-14

### *---- "Not supported when stated it was"
I paid $10 to purchase this app after looking at the specs to make sure it was supported on my device only to be immediately given a screen stating it was not supported. Under compatibility it clearly states it is compatible but I’m guessing I’ll get a robot response to this review stating that it does not state that as in an earlier review I noticed.
-- AJC575, 2022-02-24

### *---- "Bull excreta"
Description says works with 6s. 
It does not.
-- BullExcretaApple, 2020-04-23

### *---- "Said it was compatible with my phone and iPad, but was not"
Compatibility section mentioned my iPhone 8 Plus and iPad 6th gen models. Once I paid and installed it, I found out it is not compatible. I paid for the app because the free ones said that I needed an iPhone X. Not happy at all.
-- YJR13322, 2020-04-10

### **--- "Constant Ratings Nag - wild measurement results swing"
Constantly NAGS to give App Store rating ... not sure about accuracy, keeps giving readings that are between 3mm apart.  Other free “Eye Measure App” got closer to in-store doctor measurements.  Measured with glasses on and with glasses off.  Using iPhone X.
-- computerdan, 2019-09-02

### *---- "Warning needed"
The description says that you need an iPhone X (which I have) but does not explain that Face ID is used (mine doesn’t work). Wasted $3.
-- legomom07, 2019-08-11

### ***** "Easy!"
Very easy to use! Other apps seemed complicated; glad I chose this one. It does all the work for you.
-- DuffyEM, 2019-08-02

### *---- "ONLY WORKS WITH iPhone X!!! Don’t waste your $"
Only AFTER I bought this does it warn that it won’t work on my iPhone 8. Poor execution.
-- Popstar Dad, 2019-01-27
