No instructions! Ridiculous! I read first review, thought he/she was just a malcontent… no. The app is that awful ### 1/5 — Don’t waste your money *2021-09-19, version 4.0* I bought this for my grandkids after reading about what a great app this is to teach kids. I started playing with it so I would know how to help them - it’s awful! There are no instructions or tutorials explaining what to do, no voice instructions, nothing. Even worse, it freezes after every fifth or sixth attempt, so you have to restart the app and sign in. I want a refund - total waste of money. ## Frequently asked questions about World of Notes ### What is World of Notes?
