Kukuku – Next-Level Multiplication Training
▼ Description
For those who find basic multiplication too easy.
“Kukuku” is a serious mental math training app designed to strengthen your multiplication skills.
You’ve already mastered basic 1-digit × 1-digit multiplication. But when it comes to 2-digit × 2-digit or 3-digit × 3-digit, do you suddenly lose confidence?
This app is built for those aiming to go one step further—a simple yet powerful tool for advanced mental math training.
▼ Key Features
① Fully Customizable Difficulty
The biggest strength of Kukuku is its flexible difficulty settings.
From simple 1-digit × 1-digit problems to 2-digit × 3-digit, and even three-number multiplications like 1-digit × 2-digit × 3-digit—you can mix and match freely.
Start easy and gradually increase the level at your own pace. You can also focus on specific combinations you find challenging.
② Train Both Speed and Accuracy
Strong mental math requires both speed and accuracy.
Choose a time limit per question: 10 seconds, 5 seconds, or no limit.
A progress bar counts down in real time, turning red in the last 3 seconds to increase tension.
Practice accuracy without time pressure, then challenge yourself with speed—this cycle steadily improves your skills.
③ 10-Question Mode & Endless Mode
Choose how you train.
In “10-Question Mode,” your results are summarized every 10 questions—perfect for quick practice sessions.
In “Endless Mode,” problems continue without interruption, allowing deep focus and extended repetition.
Great for pre-exam training or daily routines.
④ Auto-Advance for Smooth Practice
Enable “Auto-Advance” to move to the next question instantly after entering the correct answer.
No need to press a confirm button—just focus on solving problems.
This smooth rhythm helps your brain stay in calculation mode.
▼ Learning Support Features
① Calendar Tracking
The calendar view shows your daily practice at a glance.
See how many problems you solved each day and track your consistency.
It helps build a strong learning habit by visualizing your progress.
② Performance Analytics
View your overall accuracy with a clear donut chart.
Results are also broken down by digit combinations, making it easy to identify weak areas like “2-digit × 3-digit.”
Use these insights to train more efficiently.
