The Dogl Calculus app is designed to make it easy to engage actively with Calculus, whether you're taking the course at university or high school. We believe in helping you come up with your own solutions to problems, rather than reading solutions provided by others. And since we all learn differently, the app tailors its problems to you, helping you advance at an appropriate pace.

Our content is developed by college and university lecturers and examiners — people actually teaching Calculus and creating exams — using sound pedagogical principles.
