Description by Ramkumar Vellaisamy Written by the developer, not by AppBrain. Click to read.
Eye Measure – PD Ruler measures your pupillary distance (PD) in seconds with your iPhone's front camera — and keeps all your eye records in one private place.

Measure PD in seconds
• Align your face in the on-screen guide
• The live scan detects both pupils and tells you when it's ready
• Tap Save to store the result with a photo for reference

Key Features
• Far and near PD in millimeters, decimal-precise
• Prescription Vault: photograph the front and back of your prescription and keep it next to your PD
• Expiry reminders 60 and 7 days before your prescription runs out
• PDF Report: export an optician-ready report with your PD and prescription photos
• Full history with photos, notes and search
• Share your results with your optician or online store
• On-device processing: no photos uploaded, no account required
• Available in 40+ languages

Designed for everyday use
Whether you're ordering glasses online, setting up a VR headset or keeping your family's prescriptions organized, Eye Measure makes it easy.

Eye Measure Premium
Measuring is free. Your exact PD, the Prescription Vault, PDF reports and sharing are part of Eye Measure Premium, available as an auto-renewing subscription or a one-time lifetime purchase. Premium supports Family Sharing, so one purchase covers the whole family. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage them anytime in your App Store account settings.

Eye Measure is not a medical device. Always confirm your PD and prescription with an eye care professional.
