Polyo vs OpenCube

Polyo helps you track your language study across multiple languages and skills. Log your hours. Categorize your activities. Monitor your growth.

OpenCube reads your Rubik's cube through the camera, checks that what it saw is a real cube, and shows you a solution you can follow move by move on a 3D cube. No account, no internet, nothing leaves your phone. SCAN Show each face to the camera. OpenCube uses computer vision and color matching against your cube's own six centers, so stickered, stickerless and worn cubes all read. Every solution is verified before it's shown. No camera handy? Enter the stickers by hand. SOLVE Get the shortest solution, or one in the method you're learning. Follow it on a draggable 3D cube, as a net, or as notation, one move at a time. LEARN Three complete methods: Beginner (layer by layer), CFOP and Roux. Every lesson has an animated worked example and drills that check your answer by applying it to the cube, not by matching text. The Beginner method is entirely free. TIME A competition timer with 15-second inspection, hold-to-start, WCA random-state scrambles, +2 and DNF penalties, and session ao5, ao12 and best. OPENCUBE PRO — one-time purchase, no subscription • Every CFOP and Roux stage, with solutions in the method you're learning • Full solve history, all-time stats, and stats by method • Case-specific scrambles: drill one OLL, PLL, CMLL or F2L case at a time • Practice scrambles saved from any solution • Japanese and custom color schemes Available in English, Arabic, Turkish, French, Spanish and German.
