About iDevBooks Math Apps

iDevBooks math apps are designed and made by me in Espoo, Finland.

I have been a researcher of algorithm visualization at the University of Tampere where I designed educational applications that made complex algorithms more accessible to computer science students.

The Finnish Society of Computer Science gave me the Annual Finnish Master’s Thesis Award for my thesis on algorithm visualization in 1988.

When I was looking for a Column Addition app for my daughter. I was surprised to find out that there were no apps that teach the basics like column addition, column subtraction, long division and long multiplication in an easy way.

I had designinged programs for visualizing algorithms for computer science students and I decided to use that knowledge to make great teaching and learning apps for children and everybody who wants to study math.

You wil find my apps by choosing the math apps -link. You can use the endorsements -link to find testimonials by teachers.

Core Value Proposition of iDevBooks Math Apps

All of my 18 math apps have a lightweight experience. They are optimized less around bells and whistles and more around the way how they can help students learn.

Core features of iDevBooks math apps:

no ads
no in-app purchases
wrong answers are not penalized
there are no timers, counters or a sense of rush
distractions are kept to a minimum
user feedback is valued and the apps are updated with new features based on feedback from teachers and parents
no user tracking of any kind*

* Most apps, also educational apps for children, by other developers use tracking code that enables the developers to see how customers use the apps. No iDevBooks app have ever user any kind of tracking code and never will.
