Might be good math, but not a good app – SplashLearn: Kids Learning App Review

Not worth the subscription. The hippo lets you know if you get an answer right or wrong, and says “No No!”. My kid hates the hippo’s voice. It sounds annoyed and a little mean when you get an answer wrong. Skip this and try another app unless the developer fixes that.
