Hongyi AI Cube is built for 3x3 cube solving and speedcubing practice. Enter or generate WCA scrambles, record a cube with manual six-face entry or camera recognition, and review 3D playback with solution steps. The Training tab adds a professional timer, 15-second inspection, ao5/ao12, sessions, recent solves, and long-term trends. Bluetooth mode supports tested GAN and MoYu smart cubes. After calibrating the physical cube, the in-app 3D cube can follow real turns; WCA generation in Bluetooth mode is kept as a target formula so you can scramble the real cube and verify with the net.

The AI training coach combines timer sessions, algorithm practice, and solve analysis into review advice and daily practice tasks.

Subscription unlocks AI coaching, advanced review, long-term trend analysis, and cloud sync. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
