About this app

Clever Adder is a warm, open-ended practice app where children explore the four basic arithmetic operations - addition, subtraction, multiplication and division. It is made for children in early elementary school (ages 6 to 10) and for the parents and teachers who want to help them step into the world of numbers without stress.

HOW THE PRACTICE LOOKS

Your child picks one of the four operations and a number from 1 to 10 to practice around. Clever Adder lays out a board of ten problems built around that number. Problems are solved one at a time, at the child's own pace - no countdown, no alarms, no final score.

When your child answers correctly, a green marker appears next to the problem and the app cheers: GREAT! If the answer is wrong, there is no scolding - Clever Adder patiently rewrites the problem in a simpler way, for example 3 · 4 as 3 + 3 + 3 + 3, and lets the child try again. No punishment. No frustration. No "game over".

WHAT MAKES CLEVER ADDER SPECIAL

• Practice without pressure - no timer, no score, no final leaderboard.
• Help at the right moment - when a child makes a mistake, the problem is broken into smaller steps that are easy to follow. Not a correction, a warm nudge.
• Whole-number division only - every answer is clean, no remainders, no fractions. Exactly how it is taught in early elementary school.
• Made for small fingers - large, clearly labelled keys; no tiny buttons.
• No ads. No in-app purchases. No data collection.
• Works fully offline - once installed, no Internet connection is needed.

WHAT YOUR CHILD SOLVES

Addition - numbers 1 to 10.
Subtraction - numbers 1 to 10.
Multiplication - times tables up to 10.
Division - whole-number division, no remainders.

Each operation has ten levels of practice - one for each number from 1 to 10. Forty different boards and four hundred calculations to practice.
