About this game

Calmenta is mental math and maths the other way around: your child writes the answer with a finger, anywhere on the screen, and the app reads it right away. No keyboard, no multiple choice — the gesture is the one from the school notebook.

MATH IN SHORT SETS
A set is 20 timed problems — two or three minutes of math. Enough to practice before dinner or in a waiting room, not enough to keep your child glued to the screen.

FOUR LEVELS, GRADES 1 TO 5
Beginner, Intermediate, Advanced, Extreme. From the first additions to the multiplication tables (times tables) from 2 to 12, the carries and the divisions: every math level is tuned for elementary school, and your child stays where they feel at ease. Designed for ages 6 to 11.

WHAT YOU PRACTICE IN MATH
• Addition, subtraction, multiplication, division
• Multiplication tables (times tables), from 2 to 12
• Fill-in math: a number in the problem is missing, not the result
• Comparison, powers, and the All mode that mixes the operations
• Cross math: a math grid to fill in
• Column math: the columns and the carries, in order
• Daily challenge, to revise a little every day
• Animated method cards, to learn each operation

PROGRESS YOU CAN SEE
Best times and scores, days in a row, badges, a calendar of days played, tables mastered. A reason to start again and revise your math, without the pressure of a grade.

A SPACE FOR PARENTS
For each profile: success rate, sets played, time spent. With Premium, detailed tracking: progress by operation and by multiplication table, consistency, weak spots. One profile per child, each with an avatar. Purchases and data erasure go through a parental gate.

THREE HELPERS DURING A GAME
Enlarged writing, the problem read aloud, and a memory mode — the problem is spoken, not shown. The number pad stays there for anyone who prefers to type.

AN EDUCATIONAL GAME, NO ADS, NO ACCOUNT
No ads. No account to create. Handwriting is recognized on the device: Calmenta works offline, and nothing leaves the device except purchases, handled by Google Play. A real educational math game, made for kids.
