▼ Title 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. ▼ Recommended For Students and professionals who want faster mental math Those confident with basic multiplication but struggling with larger numbers Anyone looking to strengthen math fundamentals People who enjoy daily brain training Parents who want to improve their child’s calculation skills in a fun way ▼ Data Storage All data is securely stored on your device. Your learning history is never lost, even if you close the app. You can reset all data anytime from the settings. Take your skills beyond basic multiplication. Kukuku will push your mental math to the next level. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://aquapeakstudio.com/privacy-policy
