About Pupillary Distance Ruler

Measure your interpupillary distance (IPD / PD) in seconds using the same advanced TrueDepth sensors that power Face ID.

No rulers, no mirrors, no accounts, no guesswork. Just accurate results you can trust: perfect for ordering glasses online, setting up VR headsets, or keeping track of your family’s vision.

Why Choose This App?
* Advanced Sensor Accuracy
* Uses the iPhone’s TrueDepth camera to calculate your eye centers in 3D space, far more precise than a ruler and mirror.
* Safe and Private: Your face never leaves your device. No cloud, no servers, no tracking. The app uses Apple’s secure ARKit APIs and stores only the results you choose to keep.
* Simple and Fast: Hold your iPhone in front of you, follow the on-screen guide, and get your PD in less than 10 seconds.

Free Features
* Quick PD measurement (distance PD)
* Live camera guidance with stability detection
* One-tap result in millimeters
* Educational tips on why PD matters for glasses and VR

Pro Features (In-App Purchase)
* Advanced Accuracy Mode: more samples, smarter outlier rejection, and a confidence interval with every result
* Monocular PD: measure left and right eyes separately — critical for VR headset alignment and premium glasses
* History & Profiles: save multiple results over time, track growth in kids, or measure friends and family
Export & Share: generate a professional PDF report or share your results instantly with your optician

Who It’s For
* Anyone ordering glasses online who doesn’t know their PD
* VR enthusiasts looking for the sharpest, most comfortable headset fit
* Parents who want to measure and track their children’s PD as they grow
* Optics hobbyists and tech lovers who want to see what the iPhone’s sensors can really do

Privacy First
* We believe your face belongs to you.
* 100% on-device processing
* No photos, meshes, or videos are stored
* No logins or accounts
* Only the numerical results you choose to save remain on your device

Why Pay?
* Opticians may charge $20–$40 for a PD measurement. This app gives you accurate, repeatable results for a fraction of the cost: anytime, anywhere.
