About this app

This educational app allows you to practice abacus calculation using both "oral arithmetic" and "mental arithmetic" at home every day. Let's have fun developing mental arithmetic and abacus skills with the cute abacus panda! Suitable for elementary school students from lower to upper grades, for both boys and girls.

■ Oral Arithmetic (Reads Aloud)
- Reads aloud the traditional opening phrase "Negaimashite wa..."
- Allows fine-tuning of voice (male/female), reading speed, and spacing between numbers
- Two modes: free practice (freely set the number of digits and words) and graded questions based on the abacus proficiency test (Nissho/Nisshuren)
- Switch between addition only/addition and subtraction
- Turn the display of numbers on/off while reading aloud (allows practice by listening only)
- Enter the answer for automatic scoring (can be switched to just listen to the answer without scoring)

■ Mental Arithmetic
- Graded questions (10th grade to Dan) based on the Nissho/Nisshuren/All Japan Abacus Association examination standards
- Examination mode with time limit, scoring, and pass/fail judgment
- Easy-to-read display with aligned digits, making mental and written arithmetic easier

■ Multiplication and Division
* Grade-based questions conforming to the certification standards of the Japan Chamber of Commerce and Industry, the Japan Abacus Association, and the All Japan Abacus Association (including time attack).
* For Grade 3 and above, decimal problems are also included (answers must be to three decimal places). Division is always divisible.

■ Mental Arithmetic
* Three types: mental addition, mental multiplication, and mental division.
* Grade-based questions conforming to the mental arithmetic certification standards of the Japan Abacus Association and the All Japan Abacus Association.

■ Write your answers in the squares
* Enter your answers in the squares for each digit. You can tap any square you like and write from the lowest digit.
* The number of squares is the same for each question, so the number of digits in the answer is unknown.

■ Time Attack (Mental Arithmetic)
* Challenge yourself to solve as many problems as possible within the time limit using the difficulty level of your grade.
* Freely set the time limit with the slider.
* Check your answers all at once after finishing.

■ Fun Features
* The abacus panda mascot will cheer you on.
* A lively confetti effect is displayed for correct answers and passing.
* Record your practice history to review your efforts.

■ Tablet Compatible
* In landscape mode on a tablet, the problem and input are separated into an easy-to-view two-screen layout.

■ Safe and Secure Use
* No internet connection is required (works completely offline).
* No account registration is required.
* No personal information is collected or transmitted.
* All records are stored only on your device.

Improve your mental arithmetic and abacus skills with daily practice!
