A daily arithmetic practice app for elementary school children.

It covers the full elementary curriculum from grade 1 to grade 6 as timed drills, and records your best time and best score for every course.

■ Units unlock by grade
47 units, from counting in grade 1 to ratios in grade 6. Only the units up to the grade you choose will appear, so children never get stuck on something they have not been taught yet.

■ Built for the calculation cards used as homework
90 addition cards from 1+1 to 10+9, plus the 90 subtraction cards that mirror them. Work through the same deck used at school while the timer runs.

■ Problems adapt to the child
The app looks at how quickly a question is answered, not only whether it was right, and picks problems at a difficulty that fits. Not so easy that it gets boring, not so hard that the child stops.

■ Word problems start with building the equation
Read the sentence, choose the equation, then calculate. Change a setting and the child writes the equation themselves. The answer needs a unit too, so units never get forgotten.

■ Mental arithmetic read aloud (soroban style)
Questions are read out loud and answered from memory.

■ Hints show how to think, not the answer
Number lines and diagrams show the approach. A hint never simply gives the result.

■ Mistakes come back later
Missed questions are remembered and shown again after a gap, when they are just about to be forgotten.

■ Units included
Grade 1 counting, addition, subtraction, carrying, borrowing
Grade 2 two-digit arithmetic, times tables, units of length and weight, telling time
Grade 3 division, remainders, long multiplication, large numbers, fractions, decimals
Grade 4 rounding, decimal multiplication and division, like fractions, order of operations, area, angles
Grade 5 multiples and factors, LCM and GCD, primes, unlike fractions, averages, percentages, speed, volume
Grade 6 fraction multiplication and division, ratios, area of a circle, letters in equations
Advanced positive and negative numbers, prime factorisation, classic Japanese word problems
