Summary:
Practice mental arithmetic solo or compete with friends.
Description:
Mental Math is a simple and clean app for mental arithmetic training. It’s open source and privacy-respecting, letting you practice alone or challenge your friends to compete and improve your skills.
Customizable Training
Select which arithmetic operations to include (+, -, ×, ÷). For each operation, choose from nine difficulty levels to customize your training precisely to your skill level.
Two Game Modes
Task Mode lets you complete a fixed number of tasks (10, 20, 30, 40, or 50). Timed Mode challenges you to solve as many tasks as possible within a time limit (1, 2, 3, 4, or 5 minutes).
Challenge Links
Share a link to your game either to replay a completed game with the exact same tasks and compare scores, or to start a new game with predefined settings for a fair and fresh challenge for everyone.
Difficulty Calculation
Task difficulty is determined using algorithms based on column addition, column subtraction, long multiplication, and long division, creating realistic and well-balanced exercises.
Detailed Results
After each game, view a detailed summary that includes your selected settings, your performance (accuracy, speed, and score), and a complete list of all your tasks and answers for review.
Personal Leaderboard
Your top 10 results are displayed separately for each combination of settings, allowing you to easily track your progress. You can also review detailed summaries of your top games at any time.
Game History
Explore the complete history of all your scored games. You can sort the list by time or numerically to find specific games. Anytime, you can revisit any game to view a detailed summary of its results.
Open Source and Privacy
"Mental Math" is fully open source, free to use, and does not collect or process any personal data. It requires no permissions, contains no ads, and runs entirely offline to respect your privacy.
Clean Design
A simple and minimalist app design with no unnecessary elements or distractions, designed to keep your focus fully on math training. Supports both light and dark modes.
