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. ## Rankings - #3,064,817 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `tech.lasercodesolutions.rechenhelden.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [MathHero](https://chrome-stats.com/d/com.nextgenstudy.mathhero) — 2 users - [Math Hero](https://chrome-stats.com/d/com.mathhero.app.math_hero) — 145 users - [MathWarrior - Mathe Klasse 1-4](https://chrome-stats.com/d/com.simon.mathwarrior) — 2 users - [Math Hero: Fun Math for Kids](https://chrome-stats.com/d/io.github.galitach.mathhero) — 691 users - [LernHelden Klub - Grundschule](https://chrome-stats.com/d/de.lasercode.lernheldenklub.app) — 12 users - [Math Games for Kids: Trainer](https://chrome-stats.com/d/com.learnsimpli.numberheroes) — 5 users - [Numbers — Math Trainer](https://chrome-stats.com/d/by.tigre.numbers) — 76 users - [Mathe 4.
