🧮 MATH PRACTICE FROM GRADE 1 TO 4
Math Heroes guides children from counting to written arithmetic – in 28 themed worlds with over 1300 exercises. No ads, no account, no subscription.
📚 FOUR GRADE LEVELS
• Grade 1: Numbers up to 20, addition and subtraction, shapes
• Grade 2: Numbers up to 100, multiplication tables, telling time
• Grade 3: Numbers up to 1000, written procedures, measurements
• Grade 4: Numbers up to millions, geometry, word problems
✅ EVERY EXERCISE CHECKED
The exercises aren't typed in, but generated according to rules – and then independently checked by a second program. This eliminates the possibility of incorrect answers.
⚡ MATH TRAINER
60 seconds of mental math: addition, subtraction, multiplication, or division, four difficulty levels. Set your own record.
⭐ MOTIVATION THAT SUCCEEDS
Stars for every completed task, coins to spend in the mini-shop, stickers for entire worlds, a daily streak, and 12 badges.
👨👩👧 PARENTAL AREA
Securely hidden behind a math problem: progress for each class, an overview of the last 14 days, and an analysis of which topics are still causing difficulties.
🔒 WHAT THE APP DOESN'T DO
• No ads, no tracking, no analytics services
• No account, no registration, no internet connection required
• All data remains on the device
💶 FAIR AND NO SUBSCRIPTION
The first theme world in each class is permanently free. Those who want more can make a one-time purchase – individual classes or everything together. No recurring costs, nothing is automatically renewed.
