About this app

[Developed by a Teacher! An App to Build a Foundation for Calculation]

"I can do calculations, but it takes a long time." "I can't seem to reduce my mistakes."
The mental arithmetic training app "Mastore" was created to solve these problems.

◆ Three Reasons to Choose "Mastore"

1. Pursuing Speed: "3 Seconds per Question"
Our goal is to take calculations from the "thinking" stage to the "automated, instant understanding" stage.
With instant feedback (rabbit and turtle icons) based on your solution speed, you can aim for your personal best in a game-like setting.

2. Covers a Wide Range of Ages, from Elementary School to Middle School
We provide calculation practice exercises that are useful for reviewing previous grades and for advanced learning.
・Single-digit calculations: 5 and how many, 10 and how many, addition/subtraction, multiplication, division, multiplication tables, fill-in-the-blanks
・Difficult areas: Fractions, decimals, percentages, approximate numbers
・Junior high school content: Positive and negative numbers, algebraic expressions, linear equations

3. Visualize your weaknesses with "Weakness Attack" and "Test Mode"
You can isolate and overcome your weak points, or assess your current ability with tests.

This app helps you understand your weaknesses at a glance and supports efficient learning.

・Elementary and junior high school students who want to reduce calculation errors and improve test scores
・High school students and students preparing for entrance exams who want to review their math fundamentals
・Teachers who want to use the app in the first five minutes of class
