Inaccurate
Response from developer
Thanks for the feedback. For an accurate reading, hold the phone at eye level about an arm's length away, keep the face straight and still, and measure in good, even lighting. Children tend to move or tilt their heads, so taking two or three readings and comparing them gives the most reliable result.
Inaccurate Measurements
Response from developer
Thank you for the feedback. Small variations between runs are normal, but larger ones usually come from conditions: use good, even lighting, hold the phone straight at eye level about 30 cm away, and look directly at the camera with both eyes. Taking two or three measurements and averaging them gives much more consistent results.

No wonder they asked to rate the app during the intro screen, even before you can actually use the app!
Response from developer
Thanks for sharing your concern. The subscription is presented with a free trial before any charge — nothing is billed without your explicit confirmation through Apple. The face-tracking measurement engine is what the subscription supports. If you were charged unintentionally, payments are handled by Apple and you can request a refund at reportaproblem.apple.com.
Needs subscription for anything
Response from developer
Thanks for the honest feedback. The measurement engine is the core technology of the app, which is why it sits behind the subscription — the free trial lets you test the full flow before paying anything, and the yearly plan brings the cost down significantly.
Annoyed with Apple and the App
So frustrating! Do not charge me a penny!
Response from developer
Sorry for the frustration. Subscriptions are managed by Apple rather than inside the app: open Settings → your name → Subscriptions, select the app and tap Cancel Subscription. If you were charged for something you didn't want, Apple can review it at reportaproblem.apple.com.
