Dogl Calculus: the app
Learn Calculus, conveniently
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.
Get going with no fuss
An app that fits into your everyday routine: get going anywhere, anytime. We let you work on problems in bite-size chunks so you can focus on the parts you really need.
Teacher's Eye™
See what the teacher sees when looking at a problem. Improve your pattern recognition skills to help you tackle unfamiliar problems.

Designed by university lecturers with decades of teaching experience. Customized feedback helps you understand what's going on.
