Description
IPD Measure estimates your pupillary distance (PD) in seconds, using just your phone's front camera — entirely on your device. Nothing is uploaded. Nothing is tracked.
Your PD is the distance between the centers of your pupils, in millimeters. It's something glasses opticians measure, and something VR/AR headsets ask you to know when calibrating.
TWO ACCURACY TIERS
• FREE — uses the adult-average iris diameter as the in-frame ruler. Good for most non-medical uses, no setup required.
• PREMIUM — accurate to your irises. One-time card calibration: we use a credit, debit, or ID card (ISO 7810 standard, 85.6 mm) held against your forehead as a known-size ruler to measure YOUR actual iris diameter once, saved to your device forever. Every measurement after that is calibrated to you specifically.
WHY ON-DEVICE? IPD Measure uses Google's MediaPipe iris-tracking model, running locally, to detect your irises with a 478-point face mesh — frame by frame, in real time. Three short readings are averaged for stability, with median-of-readings outlier rejection so a single bad sample (a blink, a head tilt) can't skew the result.
PRIVACY-FIRST • Camera frames are processed on your device only. • No frames, photos, or measurements ever leave your phone. • No account. No analytics. No tracking. • No internet connection required to measure.
HOW IT WORKS 1. Hold your phone at arm's length and look at the focus dot. 2. Stay still for three seconds while we capture a reading. 3. Repeat three times — we average the results for accuracy.
If you blink or shift, the timer pauses and resumes automatically. The result appears in millimeters as soon as the third reading is complete.
USE CASES • Ordering glasses online and need to know your PD • Calibrating a VR or AR headset (Xreal, Meta Quest, Apple Vision Pro, etc.) • Curiosity about your own measurements
IMPORTANT IPD Measure produces an estimate, not a medical or prescription-grade measurement. Accuracy depends on lighting, your distance to the camera, and how square-on you face it. For prescription eyewear or any official documentation, always consult a licensed optician.
IN-APP PURCHASES Premium card calibration is a one-time purchase, processed through Google Play in your local currency. The free tier remains fully functional — calibration is purely an accuracy upgrade. No subscriptions, no recurring charges.
Recent changes: General: Bug fixes for a crash that could sometimes appear after taking a photo Premium: New and improved adjustment system for the card based on user feedback

Comments on IPD Measure — Pupil Distance for Android
★★★★★Domax· Aug 9, 2026
Excellent and a must if you use a Meta Quest 3, So you can set up your eyes properly.
★★★★★Ian· Jun 2, 2026
I haven't tried the premium version yet. But the free version which is greatly appreciated seemed to keep hitting within .2 mm after like 12 scans for an average. IDK why the bad reviews. Obviously this app isn't magical and can perfectly align your head and phone. But if you try to keep the phone perfect aligned your head aligned with the level bar aka your nose shouldn't be at angle. It seems to work great. Gonna give premium a try now after that.
★★★★☆Illia· May 8, 2026
Good application, it measures the IPD and has a good design. A few things: it shows me something while I have to look at the pulsating dot during the measurement. I think it worth removing it. Critical: It gives me IPD 10 mm lower than iOS apps, with that IPD I feel uncomfortable in VR headset. Needs more testing on the precision of the measurement.
★★★★★Kathy Chatham· Jun 30, 2026
It worked! The PD was exactly what my optometrist said it was optometrist: PD 59 and the app: PD 59.1 Amazing!!
★☆☆☆☆Ken K.· Jun 29, 2026
Very inconsistent, keep getting different measurements each time that are very different. Maybe it's me but not easy use.
★★☆☆☆L· Jun 6, 2026
What is the purpose of inaccurate measuring tool? Measurements are 7 mm apart from each other depending on how close I hold the camera, and how widely I open my eyes.
★☆☆☆☆April· May 4, 2026
Can't use it at all. This is a pointless pointless pointless app. Do not use
★☆☆☆☆Thomas Jager· Jun 24, 2026
Both calibrated and with paying for the calibration using a card, this actual result was about a full cm below my actual IPD.
★★☆☆☆Mosbrg· May 31, 2026
The app functioned in the sense that nothing was broken, but the measurement was off by quite a bit.
