How to Use the App

Select a Measurement Mode:

Open the app and choose the pupillary distance (PD) measurement mode to begin scanning your face.
Position Your Device:

Hold your device at eye level and follow the on-screen guidance. Make sure your face is centered and well-lit for best results.
Initiate the Scan:

Start the scan to capture and calculate your PD using AR and TrueDepth technology. The app will display your measurement once the scan is complete.
Explore Glasses Recommendations:

After measuring your PD, view personalized glasses frame suggestions based on your facial features.

(Premium subscription required.)
Save Measurements:

You can save your PD readings in the history section for future reference. Measurement history is accessible without a premium subscription.

Pupillary Distance Display:

Once measured, your PD value will be shown clearly on-screen, helping you accurately order or fit glasses.
Personalized Glasses Suggestions:

Based on your face scan, the app recommends suitable frames to match your face shape and PD measurement.

(Premium subscription required.)
Measurement History:

Easily track, review, and manage your previous PD measurements without needing a subscription.

The app is unable to measure my pupillary distance:
- Ensure you are in a well-lit environment.
- Keep your device steady and follow the on-screen instructions carefully.
- Make sure the TrueDepth camera (front-facing camera) is not blocked.
The measurement result seems inaccurate:
- Hold your device level with your eyes and maintain a natural, relaxed facial expression.
- Re-scan if you move during the measurement or if lighting conditions change.
I cannot access glasses frame recommendations:
- A premium subscription is required to unlock frame recommendations. Please subscribe to access this feature.
My saved measurements are missing:
- Ensure you are using the same device and that the app has permission to store data locally.
