MateIA: Matemáticas para niños

MateIA is an app for children to practice math the way it's truly learned: by writing it by hand.

The child solves the problem with their finger or a stylus on an on-screen whiteboard, and Mati—a little fox acting as a teacher—reads what they've written, tells them if it's correct, and if they made a mistake, points out the step.

✏️ WRITE IT BY HAND, DON'T CHOOSE FROM OPTIONS
No selecting the correct answer from four options. The child completes the entire calculation, just like in a notebook. They can choose the color and thickness of the stylus and erase only the part they got wrong.

🦊 MATI EXPLAINS, HE DOESN'T JUST CORRECT
If the child gets stuck, Mati gives them a hint without giving them the answer. And if they wrote the steps in columns, he tells them which step they made a mistake at, not just that the result is wrong. Mati also speaks, for those who still read slowly.

📚 FROM 1ST GRADE TO 2ND YEAR OF SECONDARY SCHOOL
4 grades and 35 topics:
• First Steps (1st and 2nd grade): addition, subtraction, counting by twos, comparing, doubles and halves, simple measurements, shapes and sides.

• I Know More (3rd and 4th grade): carrying, multiplication tables, large multiplication, division, remainders, simple fractions, perimeters, units of measurement.

• Advanced (5th and 6th grade): fractions, decimals, percentages, powers and roots, greatest common divisor (GCD) and least common multiple (LCM), area and perimeter, conversions.

• Secondary School (1st and 2nd year): negative numbers, equations, rule of three, powers, simplifying terms, geometry, advanced units.

📈 THE DIFFICULTY ADJUSTS AUTOMATICALLY
Each topic has 5 levels. The level increases after 3 consecutive correct answers. If they get it wrong twice, they move down. This way, the child never gets bored or frustrated.

📖 PROBLEMS WITH A STORY
Problems tailored to the child's interests: dinosaurs, soccer, space, animals, princesses, video games, cars, or candy.

⏱️ TIME TRIAL MODE
60, 90, or 120-second games to practice quick calculations, with scoring and personal records. The timer stops while Mati checks, so the winner is the one who calculates best, not the one who writes fastest.

⭐ STARS, MEDALS, AND STREAKS
Stars for each correct answer without help, 5-exercise missions, medals, and a daily streak that encourages them to come back every day.

📊 FOR PARENTS
Statistics by topic (correct answers, incorrect answers, and difficulty level) and a weekly summary via WhatsApp showing what the child practiced, areas of improvement, and areas for further practice.

🔒 DESIGNED FOR CHILD USE
• The account is created and managed by an adult using their mobile phone or Google account.

• We only store the child's first name and topics of interest.

• Photos of the whiteboard are NOT saved: they are used to correct exercises and are then discarded.

• No advertising, no social media links, and no chat with strangers.

• Sharing, logging out, or deleting the account requires adult verification.

Mati uses artificial intelligence and, like all AI, can make mistakes. The app includes a button to report any incorrect or inappropriate answers, and we review these reports.

MateIA requires an internet connection for Mati to review the whiteboard.
