## What is PDgo?

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

WHAT YOU GET
• Total PD plus left and right monocular PD
• Near PD conversion for reading distance
• A confidence rating based on measurement stability
• Local history — rename, search, and review your measurements anytime
• Lens guidance: index, coating, and shape suggestions based on your prescription

PRIVATE BY DESIGN
• All processing happens on your iPhone
• Camera frames and depth data are never uploaded
• No account, no sign-in required

REQUIREMENTS & ACCURACY
PDgo requires an iPhone with Face ID (TrueDepth camera). Results are a reference for ordering eyewear and talking with your optician — for medical decisions, please rely on a professional eye exam.

PRICING
Unlock your result with a one-time purchase, or get unlimited measurements with a yearly plan. Prices are shown in your local currency at checkout. The yearly plan auto-renews and can be canceled anytime in your Apple ID settings.
