Only for iPhone
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Your PD, measured automatically and accurately in 10 seconds. Just open PDgo and tap Start Measuring. Everything else happens on its own. Nothing to figure out.
PDgo measures your pupillary distance (PD) in seconds using your iPhone's TrueDepth camera — no ruler, no mirror, no guesswork.
Most online optical stores ask for your PD when you order glasses. PDgo gives you a reliable reference number right from your phone.
HOW IT WORKS
1. Align your eyes inside the on-screen guide
2. Hold still — PDgo automatically captures three rounds
3. View your result and it's saved to your records
