It almost pains me to write that title. I make apps to help students, I have about 12 of them on both Google and Apple and they are pretty good. None of them are the one I am talking about here though. Here is is all about Teach Your Monster to Read made, and made really well, by Usborne in the U.K. The links are all at the bottom for the app and website.
There are more than 10 great English apps on the Google Playstore and Apple App stores. Apps like Teach your monster to read and Phonics hop and pop are great but there are more options out there with out pay walls. Here we talk about 10 of them.
