## Description

PD Measure is a highly-rated app that calculates Pupillary Distance (PD) quickly and accurately. It provides four PD modes—Distance PD for everyday glasses, Reading PD for reading glasses, Computer PD for desktop use, and VR PD for headsets—powered by advanced algorithms and automatic pupil detection.

The app supports automated and manual measurements. On iPhone X and newer, PD can be detected automatically in under 3 seconds; on older models, users follow a simple 3-step process. Thousands of satisfied users praise its precision, helping you order glasses online faster and cheaper.

## Review summary

Reviews show a divide: many praise the app for being quick, easy, and sometimes accurate enough to order glasses online, with it matching eye doctor PD for some users. However, many report inconsistent results, accuracy issues, crashes, and price discrepancies. The app can be a convenient PD tool for online purchases, but reliability and stability concerns are a major downside for a substantial portion of users.

### Pros

- Quick and easy to use for measuring PD
- Can match eye doctor PD for some users, enabling accurate online glasses ordering
- Useful workaround when doctors won’t share PD, potentially saving time and money
- Locks onto pupils quickly and reduces need for manual reference measurements
- Considered one of the better free/low-cost PD apps by some reviewers

### Cons

- Results are inconsistent and vary between attempts, reducing reliability
- Accuracy is often questionable, with reports of errors of several millimeters
- Frequent crashes, black screens, or freezes that prevent use
- Pricing inconsistencies and being charged more than listed
- Lack of clear instructions on how to use (where to look, distance, etc.) and some usability issues for kids
