About KidsDoMath
KidsDoMath was created by parents who were frustrated with the math apps available for young children. Most were either loaded with ads, collected personal data, required subscriptions, or buried the actual math under layers of distracting animations. We wanted something better.
Our Mission
Every child deserves access to high-quality math practice — regardless of their family's ability to pay. KidsDoMath is 100% free, with no ads, no in-app purchases, and no data collection. It will stay that way.
How It Works
KidsDoMath uses two proven learning techniques: visual arrays that help kids see what multiplication, addition, subtraction, and division actually mean, and spaced repetition that ensures facts move from short-term to long-term memory. Together, these approaches help children build genuine understanding, not just rote memorization.

Privacy First
We believe children's apps should collect zero personal data. KidsDoMath stores all progress locally on the device — nothing is ever sent to a server. There are no accounts, no tracking, and no analytics beyond anonymous page-view counts. Read our full privacy policy.
Built for Ages 5-8
Every design decision — from the large, colorful buttons to the kid-friendly characters — is made with young learners in mind. Sessions are short (3-5 minutes), difficulty adapts automatically, and the app works fully offline as an installable PWA. It's perfect for car rides, waiting rooms, or a few minutes before school.
The Science Behind KidsDoMath
KidsDoMath is built on proven learning science, not guesswork:
- Spaced repetition — Based on the Leitner system (1972), facts move through five boxes as children master them. This method leverages the spacing effect first described by Hermann Ebbinghaus to strengthen long-term memory.
- Visual arrays — Research shows that representing multiplication as rectangular arrays helps children build conceptual understanding rather than relying on rote memorization.
- Short, frequent sessions — Cognitive science consistently finds that distributed practice (3-5 minutes daily) outperforms massed practice for young learners.
- Immediate feedback — Children see results instantly, reinforcing correct associations and gently correcting mistakes before they become habits.
Who Built This
KidsDoMath was created by a parent and software engineer who couldn't find a math practice app that was genuinely free, ad-free, and focused on understanding over memorization. After watching a child struggle with multiplication flash cards, the idea was simple: build something better using real learning science — and give it away for free.
Open & Transparent
The entire KidsDoMath codebase is publicly available and open-source. You can inspect exactly how the app works, verify our privacy claims, and even suggest improvements. We believe educational tools for children should be transparent and accountable.
