Welcome
Hello 👋🏼 I'm Chris Dempewolf, founder of Dempewolf Apps.
I create simple yet customizable, research-backed cognitive training tools for people of all ages. Whether you want to practice mental math, memory (short and long-term), or even prepare for a competition—I've got you covered!

Athena Math
Athena is a mental math training app. Mental math helps improve problem-solving skills, develops number sense, and even enhances working memory.
As society increasingly delegates calculations to devices, Athena Math aims to bring back the power of mental computation.
