Great for children with CVI
I have made a flash card set with familiar objects for my child and used the simple preschool cards. It is not perfect for the child with cortical visual impairment but it is the best I have found so far. Some of the pictures and letters are very simple. The touch is very sensitive for children with motor impairments. Also a ton of customization. Great for any child. You can add sounds to the cards. Easy to import photos from library. Overall a really great app. And it rarely crashes. Try the free version (which is awesome) and update if it suits your needs.
