Maths practice kids actually ask for.
Four operations, seven ways to play. Kalkulo Play turns times tables and long division into short, winnable rounds — and quietly shows you where your child is getting stronger.
The four operations
Start where your child is.
Pick one operation or blend them. Every mode below works with whichever you choose, so the app grows from single-digit addition all the way to long division.
Addition
Putting together
+Subtraction
Taking away
−Multiplication
Groups of
×Division
Sharing out
÷Mixed
Blend operations
∞Drills
Twelve questions. No repeats. Beat your own time.
A round is short enough to finish before anyone loses interest, and the clock makes it a game against yesterday rather than against a classmate. Missing Number flips the equation around so children have to reason backwards, not just recall.
- Speed Drill — 12 questions, no repeats, one timer.
- Missing Number — solve for the blank, either side of the equals sign.
- Mix & Math — you choose the left and right number sets.
Games
Answer before it lands.
Math Meteor gives a question a falling deadline and three lives. It is the mode that turns a reluctant five minutes into a requested twenty — and because the questions come from the same engine as the drills, the practice is identical.
- Three lives, rounds that get faster as the score climbs.
- Difficulty follows the operation and number range you set.
- No timers on the menus — pressure only inside the game.
Duel Mode
Two players. One phone. First to answer wins.
Hand the phone across the table. The screen splits, both players get the same question, and the fastest correct answer takes the point — Classic, Missing Number, or True or False.
- No second device, no account, no internet.
- Great for a parent and child at very different levels.
- Three duel types, so it stays fresh.
Seven ways to play
Learn it, drill it, then play it.
The menu is deliberately shallow. Two taps from opening the app, a child is answering a question.
Tables
Walk through the tables from 1 to 12 at your own pace, with no clock running.

Twelve questions, no repeats. The only opponent is your last time.
DrillMissing Number
The blank moves around the equation, so recall alone will not carry it.
DrillMix & Math
Choose the left and right number sets yourself — target one weak spot.
DrillMath Meteor & Duel
The two game modes: beat the falling clock, or beat the person opposite.
GameFor parents
Safe by construction, not by policy.
The safest way to handle a child's data is not to collect it. Kalkulo Play has no accounts, no ad networks and no behavioural tracking — and everything that matters is decided by an adult.
No ads, ever
No banners, no rewarded video, no pop-ups between rounds. Nothing interrupts a question.
Profiles stay on the phone
Names and progress never leave the device. Leaderboards are optional and carry only an anonymous nickname, age and country.
Plays offline
Every lesson, drill and game runs locally — on a plane, in the car, or on a phone with no SIM. Only leaderboards need a connection.
Adults hold the keys
Purchases, profile setup and every outbound link sit behind an adult parental gate. No coins, no gems, no pay-to-skip timers.
Five minutes a day is enough.
