## What is Klasito?

Math for grades 1 to 12: times tables and long division, then Algebra I, Geometry, Algebra II, and the start of calculus and statistics.
When your child gets one wrong, the app explains the mistake and gives up to three hints. Formulas go in the way they look on paper, and each line of an equation gets checked.
Free, with no ads or purchases. Works offline.

WHAT KIDS PRACTICE, GRADES 1–12
• Grades 1–5: addition and subtraction with regrouping, times tables, mental math, long division digit by digit, fractions, decimals, measurement, coins and data.
• Grades 6–8: ratios and percents, signed numbers, expressions and equations, linear functions, the Pythagorean theorem, volume, statistics and probability.
• Grade 9, Algebra I; grade 10, Geometry with proofs; grade 11, Algebra II with exponentials, logarithms, the unit circle and conic sections.
• Grade 12: limits, derivatives, first integrals, and statistics (samples, the normal distribution, correlation). This grade covers part of a full course.
You pick the grade and can change it at any time.

HOW IT HELPS
• A formula keypad: fractions, powers and roots look the way they do on paper.
• Equations line by line: the app checks each line and shows which one has the mistake.
• Graphs: plot points and drag the line or the parabola into place. A unit circle for trigonometry.
• 3D solids your child turns with a finger, and proofs built step by step, each statement with its reason.
• Simulations: flip coins and roll dice many times and watch the frequency settle near the probability.
• Every topic has a theory card, 3 levels and three hints per problem: a nudge, the rule, a worked example.
• Typical mistakes come with an explanation. Add the numerators in 1/2 + 1/3 and the app answers: "You can only add numerators when the denominators are the same."
• Mastery levels for each topic: Tried, Familiar, Proficient, Mastered.
• A mixed test for every floor and a tower exam at the end of the grade, with a certificate.
• Review after 1, 3, 7, 14 and 30 days, a daily warm-up, timed mental math and the Times Tables Minute.

WHY KIDS COME BACK
• Each grade is a tower. Lessons light its windows, and each finished floor lets your child pick a new department for their company.
• The 3D arena grows as they practice, and they dress their own 3D player.
• The team: Axel the axolotl, Leo and Vale join as the windows light up. One cheers your child on from the sideline and celebrates their baskets.
• The Stage: a dance battle with Vale to 22 tracks, from cumbia and mariachi to salsa and disco.

FOR PARENTS
• In "For parents" you see what your child has down and what needs more work, topic by topic.
• "Ready for class": mark the topic the class is on, and the daily warm-up reviews it and previews the next one.
• No account. Progress stays on the device, and we collect no data.
• A grown-ups question comes before any link and before turning on the daily reminder (off by default).

Bonus: Spanish lessons for kids who speak Spanish, and English (ESL, A1–A2) for Spanish speakers, grades 1–6. The app is in English, Spanish and Russian.
Klasito is made by a family in Mexico.

## Version history (last 5 releases)

### 2.6.0 — 2026-11-10

What's new in 2.6:
• Weekly Cup with other kids: a parent switches it on in the Parents area, and you compete with a fun nickname in a group of your age, by the points you earn learning. It's optional and off by default.
• A new home screen: a bigger player, the path of your floor's windows and one button to keep going.
• A softer look across the app.
• My week: every day is a ball that fills up with your points.
• Much smoother dribbling in the arena, and sharper cups.

### 2.5.0 — 2026-11-09

What's new in 2.5:
• Tournament of the week: pick your goal, earn tournament points by learning and win a bronze, silver or gold trophy every week. Points come from right answers, new steps, reviews and fixed mistakes; speed doesn't count.
• My weeks in My arena and a weekly summary for parents.
• When you load a progress file, Klasito first shows what's in it and asks before replacing anything.
• A cleaner player and ball in the stadium: no black outline, knee pads that follow the leg, a spotless kit and shoes, and the player stays in one piece in every move.

### 2.4.0 — 2026-11-08

What's new in 2.4:
• Klasito now works on iPhone Duo: on the outer screen and on the big inner one, with more room for the notebook, long division and the stadium.
• Cleaner moves in the stadium: nothing sinks into the floor, the ball stays out of the head and the feet no longer skate on turns.

### 2.3.0 — 2026-11-07

What's new in 2.3:
• Practice for the Mexican admission exams: UNAM, IPN, EXANI-I and EXANI-II.
• High school: matrices, complex numbers and polynomials.
• Different fans in the stands: they sit, clap and cheer every basket.
• Alley-oop: Axel or the coach lobs you the ball and you slam it home.
• If you play with Axel, he sometimes bounce-passes you the ball.
• Your player picks up the ball with both hands.
• Two new dunks.
• A button to turn the stadium sound off.
• 78 new trophies, each with its own drawing, and silhouettes of the next ones.
• On tasks with figures, the keypad no longer covers the drawing.
• Smoother, steadier moves.

### 2.2.0 — 2026-11-05

What's new in 2.2:
• The stadium sounds like a real arena: a real crowd, the swish and the bounce of the ball. The more you learn, the louder it gets.
• The stands fill up bit by bit: one fan comes first, and as you learn the whole crowd arrives.
• After a shot your player runs to the ball and picks it up. New dribbling tricks.
• More math: middle and high school, with more topics and theory.
• Times-table minute and seasonal challenges.
• Fixes and improvements.
