Great for speech therapy as well!

I am a speech therapist, and I downloaded this app and the Rocket ABCs. I have been using them for an adult patient with a reading impairment (alexia) and a vision impairment (field cut). It has been fantastic. The format is simple enough that she can understand what she’s supposed to do and the graphics are well done but not too immature for adults. She really enjoys it. If I were working with a child learning his/her numbers, I would definitely recommend it as well since teaches them to identify the numbers in a variety of contexts/orientations.
