I have been looking for a great app like this that doesn’t have a pro or premium version that they try and push on you. Thank you! Thank you!

Thank you so much for the kind words! Because it’s free, I work on it whenever I get time but I’ll make sure to continue getting new games and features out there. If you have anything specific that you’d like to see, feel free to message 🙌🏼 - Raj

Wonderful app!

Great app to keep the kids busy during quarantine. We have a competition to see who has the most correct in 1 minute. Can see the kids get faster with their mental math the more they practice.
