What this is
An educational tool that applies published research about infant vision and hearing to a camera frame or a sound. It is provided as is, for information.
Not a medical device
This is not a vision or hearing test, a screening tool, or an assessment of any kind. It describes what research says about babies in general and never evaluates your baby. If anything worries you, speak to your paediatrician or a paediatric eye doctor.
Purchases
The one-time unlock grants every feature, permanently, on the store account that bought it. Refunds are handled by the store you bought it from, under that store’s policy.
Unlock codes
A valid unlock code grants every feature permanently and free. It is honoured for as long as the app exists, and a code already redeemed is never revoked by a later change to what is sold.
Liability
To the extent the law allows, this app is provided without warranty. It cannot and does not tell you anything about your own baby’s sight or hearing.
If this document changes, the date above changes with it, in the same release.
