IPD Measure is a free Android application designed to estimate pupillary distance (PD) using your phone's front camera. This productivity tool operates entirely on-device, ensuring that your measurements and camera frames remain private, as nothing is uploaded or tracked. The application utilizes Google's MediaPipe iris-tracking model to detect your irises, leveraging the average human iris size to create an accurate ruler for measurement. Users can perform the measurement process in just a few seconds, providing a convenient solution for those needing to know their PD for glasses or VR headset calibration.

The app is straightforward to use: simply hold the phone at arm's length, focus on a dot, and remain still for three readings, which are then averaged for accuracy. While the app produces an estimate rather than a medical-grade measurement, it is a handy tool for various use cases, including online glasses ordering and personal curiosity. With no ads or in-app purchases, IPD Measure offers a user-friendly experience, prioritizing privacy and ease of use.
