Ratings and reviews

Great - but no sound

Great app. My daughter is absolutely thrilled.
Why there is no sound to the app on the iPad (unlike on the iPhone) is incomprehensible.

Sewing machine23,

The app is great, our little one has already made good progress!

It should be set, however, that when calculating up to 100, it should be calculated without carrying over. That's the way it is with us at school, the kids already calculate up to 100 in the first year of school, but then without carrying over tasks. And the setting only tasks up to 10 would be great because in Saarland the children only calculate up to 10 in the first and then directly up to 100 without carrying over

That would be the perfect app if that were retrofitted!

Suburban children,

Smart app for the older ones too

Lovingly designed app in which our 9-year-old daughter also has a lot to work on. The number range up to 100 is already quite demanding. The adjustable number range (20, 50, 100) and the selectable task types (only plus, only minus, plus and minus, etc.) are practical. So the younger ones are not overwhelmed either. We always have several children competing. And the adults can see whether they can calculate faster than their children! This app trains the understanding of numbers and (fast) mental arithmetic in a playful way. In between and over and over again. Brilliant! The ideal addition to math lessons. Predicate: valuable!
