My daughter learned the alphabet way faster than all her cousins and I think it was because I let her use the Endless Alphabet app. Kids have a blast learning their ABC’s and building vocabulary with the adorable Endless monsters. Each word features an interactive puzzle game with talking letters and a short animation illustrating the definition. I used the in-app purchases to get all the words. Well worth it.
The app is by Originator Inc. Their “Endless Reader” and “Endless Wordplay” apps are similar and just as good. I also purchased the BeBop Blox app. That has fun for her for a week, after that she mostly just wanted to use Endless Alphabet the whole time.
