Krokuj – Maths for Kids
Discover numbers step by step
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Krokuj is a calm maths game for children aged 6 to 8 (first and second grade). Instead of drilling facts, children discover maths in environments they love coming back to.
SIX WORLDS
• Bus: people get on and off. How many are inside?
• Addition triangles: numbers that fit together.
• Snakes: steps up and down the number line.
• Cube buildings: floor plans, columns and counting cubes.
• Stepping: the hedgehog walks forwards and backwards over stones.
• Puzzles: number triples, addition tables, the gnome’s equations and podium orders, often with more than one solution.
LEARNING WITHOUT PRESSURE
• No timers, no points, never “wrong”. When something doesn’t fit, the hedgehog says where, never what.
• Every correct solution counts, even one you didn’t expect.
• Hints show how to think, not the answer.
• Tasks are generated, so they never repeat. Difficulty rises by itself and never drops.
REWARDS THAT ONLY GROW
A journey map, a sticker album, badges for exploring, a gallery of the child’s own work, the hedgehog’s story and a house of their own that slowly grows into a whole village. Nothing can be lost or bought.
FOR PARENTS
• Level 1 in every world is free forever, with unlimited new tasks.
• The subscription (monthly or yearly, first 7 days free) opens levels 2 and 3 and everything new we add. It covers every child on the device and works with Family Sharing.
• Several children on one device, each with their own animal and progress.
• For each child you choose the grade (preschool, first or second grade) and the pace at which harder tasks arrive.
• Settings and the subscription sit behind a parental gate. Children never see a price or an offer.
• No ads, no analytics, no accounts. Optional sync through your own private iCloud.
• In Slovak, a recorded voice reads the instructions and feedback. The app is in Slovak and English.
Schools can use Krokuj for free. Write to skoly@krokuj.sk
The subscription renews automatically unless you cancel it in your Apple Account settings at least 24 hours before the end of the period.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Krokuj has a new painted look: home is the hedgehog's valley, every world has its own scene, and the hedgehog in his red scarf talks. The bus is a double-decker and passengers sit in fives and tens, so a number is seen at a glance. A new journey map, stickers, little houses in eight looks and a village. Diplomas for every level. For parents: a first-time setup, a weekly summary and a star when your child is ready for more.
