Description by Haruhiko Kishi (from the App Store)

Practice flash anzan (flash mental arithmetic) in the same format as the Japanese grading exam—and climb the ranks.

GRADED MODE (30 RANKS, KYU 10 TO DAN 20)
Each rank uses the exam's total-time format: numbers flash within a fixed total time, you answer 10 problems, and 70 points is a pass. Kyu 10–8 are free, and every higher rank includes one free try. A single one-time purchase unlocks all ranks (no subscription).

YOUR GRADE IS KEPT
Your best rank is recorded on the device and in iCloud, so it follows you to a new device.

ANSWER BY VOICE
Type on the number pad, or just say the answer. Speech recognition runs entirely on your device—your voice is never sent anywhere.

FREE PRACTICE
Set digits, count, and display time yourself—from slow single digits to 3-digit numbers at 0.3 seconds.

IPHONE, IPAD AND MAC
One purchase covers all three, and your grade follows you between them through iCloud.

No ads. Available in nine languages: English, Japanese, Chinese (Simplified and Traditional), Korean, German, Spanish, French and Brazilian Portuguese.

Note: This app is not affiliated with or endorsed by any certification body.
