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. CFOP practice covers Cross, F2L, 2-Look OLL, and PLL with case recognition, algorithms, and 3D follow-along playback. The AI training coach combines timer sessions, algorithm practice, and solve analysis into review advice and daily practice tasks. Free features include WCA timing, local sessions, ao5/ao12, basic CFOP practice, 3x3 solving, and 3D demos. 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/
