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.
