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. 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. CUSTOM PRACTICE Set digits, count, and display time yourself—from slow single digits to 3-digit numbers at 0.3 seconds. IPHONE DUO Big numbers when it's open; fold it in half and the question sits above with the number keys below. Close it and keep practicing on the outer screen. IPHONE, IPAD AND MAC Works on iPhone, iPad and Mac, and your grade follows you between them through iCloud. No ads.
