Hi everyone!
I've been working on a free app for learning and training CFOP and Roux algorithms, and I'd love to get some feedback from the community.
What it does:
• 176 algorithms total — CFOP (F2L 41, OLL 57, PLL 21) and Roux (CMLL 42, LSE 15)
• Visual previews — 3D cube for F2L, top view with arrows for OLL, PLL, CMLL, LSE
• Trainer mode — pull cases from your favorites, generate a scramble, and solve against the clock
• Stats per case — best time, avg of 5, avg of 12, and recent history
• Search and favorites
• 9 languages (English, Русский, Українська, 中文, Español, Deutsch, Français, Português, Italiano)
• Dark mode
• Responsive layout — works on phones, tablets, and Windows
All algorithms were cross-checked against SpeedCubeDB, CubeSkills, and other trusted sources. Scrambles are computed automatically as the inverse of each algorithm.
Downloads (free, no ads, no tracking):
• Android APK: https://github.com/cellonty/cube-trainer/releases/latest
• Windows EXE: https://github.com/cellonty/cube-trainer/releases/latest
• Source code (MIT): https://github.com/cellonty/cube-trainer
The APK is signed with my own release key. Windows users may see a SmartScreen warning — just click "More info" → "Run anyway" (this is normal for indie apps without a paid certificate).
I'm open to any feedback — bugs, missing features, UI suggestions, or just general impressions. If you find something wrong with an algorithm, please let me know so I can fix it.
Thanks for reading, and happy cubing!
