Aritmo

Train your brain to calculate faster with short, structured mental math lessons.

Aritmo teaches rapid calculation techniques through focused lessons, interactive practice, and gamified challenges. Instead of memorizing random tricks, you learn step-by-step methods for solving arithmetic problems more efficiently in your head.

LEARN MENTAL MATH STEP BY STEP

Aritmo is designed to help you build real calculation skills through progressive courses and practice exercises.

In this first version, Aritmo includes two main learning paths:

• Basic Multiplication
Learn the Trachtenberg method for rapid multiplication with numbers from 2 to 11. This course introduces the core patterns and rules used to multiply faster mentally.

• General Multiplication
Learn a broader multiplication method for solving more flexible multiplication problems. This course is available with an active subscription.

The app clearly identifies which content is included and which content requires a subscription before purchase.

PRACTICE WITH SHORT DAILY LESSONS

Each concept is broken into simple lessons that can be completed in a few minutes. You can learn a method, practice it immediately, and repeat challenges to build speed and confidence over time.

Aritmo helps you practice:

• Fast multiplication techniques
