Kay Say and Match App

New update now available for iOS and Android!


The Kay Say and Match app provides a fun way to help very young children to practise and learn the Kay Picture optotypes which are used to measure children’s vision before they know capital letters. The app is aimed at children from 15 months of age who are just learning to talk, and to help children over 24 months learn to match.

Learning the picture names and the concept of matching improves a child’s confidence to perform the picture vision test at the earliest possible age. There are four games in the Kay Say and Match app, three of which are free to download and use. The fourth game is an in-app purchase for a one-time small fee.

The Name game teaches the names and sounds of the six Kay Picture optotypes with the help of a friendly Mr Fuzzy character. Knowing the picture names will give the child confidence to perform a professional vision test earlier than otherwise.

The Match games help children to learn the concept of matching the same picture, which may be useful during a vision test if the child is shy or non-verbal. The games are fun and easy, with sounds and cheering rewards.

The Practice game simulates the vision testing process, where the picture to be matched is shown separately, remembered, then matched.

The Test game is an in-app purchase. This provides a speaking matching card to be used during a professional vision test. Each picture says its name when touched, making it easier for the examiner to hear which picture has been chosen, and more fun for the child. This is particularly helpful for children with some additional needs such as autism.
