Handwriting and feedback great
I think including handwriting makes this the best times table app for building "automaticity" (subtitizing, quick mental calculations,etc) in arithmetic.
But I miss the three stars to fill in at each level that you see in Quick Math +
That feature makes kids go back in and repeat each level until they achieve some kind of mastery. In this Quick Math version there is no feedback on when you have mastered a level: "beginner, intermediate, etc."
