This is a useful app for students who know or are learning calculus to reference formulas or theorems as they are problem solving, but parents should not expect students to learn or better understand calculus using this app. The navigation is straight-forward with a clean, easy to read layout. Each rule or theorem gets its own page displaying the rule in mathematical terms. In some cases, but not most, there is supporting text, diagrams or examples. Students who struggled understanding the concepts will not be helped by this app, but students who simply need to refresh their memories about the formulas and how to apply them may find this a helpful, easy to use reference tool.
