Apps made with care

Strum App Development is an independent app studio in the Netherlands. We create thoughtful, easy-to-understand experiences for children and families.

Our first game, Fraction Pizzeria, turns fractions into a hands-on pizza adventure. We keep instructions clear, avoid advertising and tracking, and give parents straightforward information about purchases, support and privacy.

Clear for families

We design each app to be easy to understand, calm to use, and respectful of privacy. Purchases are explained clearly, and parents and caregivers can reach straightforward support.
