Math your child will actually understand

Interactive lessons with animations, exercises with step-by-step guided solutions, and an assistant that teaches children to think — not just hand them answers. The whole 5th-grade curriculum in one place.

The app works in Polish, English, and Ukrainian — built for Polish children, English-speaking children studying in Poland, and children from Ukraine.

What's inside

Everything your child needs to learn math independently and actually understand it.

📚

Interactive lessons

10 chapters covering the full 5th-grade curriculum, each with animations that show step by step how a concept works.

✍️

Guided exercises

Problems with solutions broken into steps — your child sees the path to the answer, not just the answer itself.

🖨️

Printable PDF worksheets

Ready-made exercise sets to print and solve offline — great for reviewing before a test.

🏅

Badges and progress

Your child can see their progress chapter by chapter and earn badges for completed lessons.

🎨

4 visual themes

Friendly, Pixel, Storybook, or Clay — your child picks the look they want to learn in.

🌍

3 languages

The whole app runs in Polish, English, and Ukrainian — your child learns in the language they're most comfortable in.

🎲

Assistant generates new exercises

When your child asks for another example, the assistant invents a fresh, similar problem to practice — no more repeating the exact same content.

🔁

Learn at your own pace

No time limit, no pressure — your child can return to the same lessons and exercises as many times as it takes to truly understand a topic. Parents can finally relax.

The assistant's philosophy

The assistant guides. It doesn't solve the problem for your child.

When a child gets stuck on a problem, the assistant doesn't just hand over the answer. It asks guiding questions, reminds them of the rule they need, and nudges them toward the next step — the way a good tutor would, someone who actually wants the student to understand the topic, not just tick a box.

That difference matters: your child leaves every study session a little smarter, not just with a finished worksheet.

I'm stuck on question 5. How do I solve it?
Let's start with what you already know: what's the GCD of 12 and 18? Try to find it, and we'll take it from there.
