Nice app, small problem.

My daughter has been using this app for months now, and it’s had the same problem. It keeps crashing just when she is about to win a minigame and it makes her a bit frustrated. But, it only happens with one game, so I gave it a four star. Other than the crashing problem, the app isn’t bad at all! I can see her grades improve bit by bit, and it makes me happy. I haven’t seen other people write reviews about this problem, so I think it’s just a small bug. But, I definitely recommend it.

Sorry to hear about that! We'd love to hear more details about which specific lesson this is happening in. Could you email us at with details so we can get it fixed?

It’s a really good game!

When I started playing this game I was exited!!!! There is so much things that you can do. Like magnets, angels, reading and much MORE!!!!!!!! This is a great learning game if your on the go or sick you can still learn. If people comment stuff like it’s $20 per year for the full version it’s not true because that’s if you want 200 more games to play! It’ $4 if you only want to get all this 18 games. Also you don’t have to pay per year or month!!! Another reason I love this game is because it’s not like IXL when your being graded and you drop back wayyyy to many points. It’s way different from all those school apps. It’s pretty cool that this app can work with no WiFi! DO NOT listen to the bad reviews!!! These games make you learn and it’s not hard to control the fraction game, and the vowel one does end!!!!! Soooo do not listen to bad reviews!! It’s rude to the creator who mad this game!!!!!! I don’t think that this creator needs to add anything!:3 bye!!!!!!

Really recommend

This is the game my daughter used throughout the year, she improved a lot and she got strait A’s! Parents, I really recommend your child at least playing this for an hour. Both my girls are playing this, I can’t wait to get the next app, 5th grade. My kids love this game so much! 🤩
Note to parents: if your kids have a hard time on the app, please work it out and talk to them about what’s going on, either in the story, or spelling. If your kid is not interested in the game, try to do something fun, like the racing game! If you have a son, you can always play the racing game. If you have a daughter, you can do reading on the topic of dogs. You can use this app anytime, and anywhere. This game is the reason my daughter got strait A’s! And she was fantastic in both classes, because this game has all the subjects a 4th grader will need. Totally recommend, and without anything else being said, have a great time with this app!
