Why We Made This App

Our son had a toy keypad which recognized about twenty 3-letter words and played an audio clip when recognized words were typed. It came with a picture book to show these 3-letter words as well. He loved it and quickly learned how to type those words. The problem was that he started to type words which the toy didn’t recognize, even though some of those words were in the book.

Me and my husband wanted to encourage his passion for spelling. We looked everywhere for apps or toys that did similar things, but we were not able to find anything. The closest thing we found was a toy from the 70’s called “Speak N Spell”, but it was no longer made.

So I decided to make my own app. I first found a database of existing 3-letter words, and then chose one hundred that were kid-friendly, drew pictures and asked my husband to record narrative for each.

It was a great experience creating this app, and I’m very happy to say my son loves it. Especially funny words like pee and poo! I’m hoping that other kids will enjoy this app as much as he does.
