Bottom Line: A quiz-style app that may be useful for parents and teachers, but might not be motivating enough for students. A few areas need improvement, but it's Free to try all seven content strands!
Bottom Line: When your children have moved on from memorization of basic math facts and need support with math from Grade 4 through college, then look no further. This app has the answer to the most complex of problems free and thorough explanations for a fair price.
Bottom line: If you're in the U.K. and have a 7 to 11 year old child, buy it. If you're elsewhere and have a child functioning in that age range, still take a long look, especially since you can try the basics for free.
