Simple yet helpful!
For a very short period of time, it helped my daughter improved her mental mathematical skills especially multiplication. It has so many useful exercises that will truly challenge your kids to learn more. My only suggestion here is if we could change the format of the questions/equation. e.g. in (table of 3) it is written as 5 x 3, 4 x 3, 2 x 3... instead of 3 x 5, 3 x 4, 3 x 2...it confuses not only me but also my daughter. But overall it is a great affordable app!
