XC Master · Pro 3x3 Cube AI Trainer Connect a smart cube and every turn is recorded, broken down, and analyzed. AI reads each of your solves, stage drills target your weak spots, algorithms get drilled case by case, and you can race cubers on other brands of smart cube in real time — on speed or on move count. Completely free · No ads · No push notifications — just focused practice. [Smart Practice] Works with Bluetooth smart cubes from all major brands. Automatic timing with a per-stage split of time and moves for Cross, F2L, OLL, and PLL, slice-move (M / E / S) recognition, and a rating for every solve. Give the cube a quick back-and-forth twist to start the next solve. No need to solve it first — XC Master works out the moves from wherever your cube is to the next scramble. [AI Solve Insight] A full AI analysis of your actual solve, stage by stage: it finds wasted moves, likely slips, and F2L pair choices, then coaches you with concrete things to practice. Tap "Try again" to load the same scramble right away. Practice becomes more than a number on the timer. [Live Battles Across Brands] Smart cubes from different brands compete in the same room, and your opponent's 3D cube turns live with every move they make. • Race by time or by moves: fastest hands win, or fewest moves win • Handicaps in seconds or moves: stronger players give a head start, so every match stays close • Free, Ao5, or Bo3 format, chosen when you create the room • Join by QR code or room code, and watch as a spectator when the room is full [Smart Stage Practice] Drill Cross, XC, F2L, and CF separately — each attempt ends as soon as that stage is done: • Cross can be measured against the best solution, within a tolerance you choose • XC only counts as a true XCross — solving the cross first and then the pair doesn't qualify • F2L scrambles start with the cross already solved, so you go straight to the pairs • Practice on any of the six colors, with move- or time-based goals you set [Algorithm Library & Practice] F2L, OLL, PLL, WV, ZBLS and ZBLL libraries with case diagrams and step-by-step 3D demos. Each case offers standard and community-shared solutions — set your go-to and it syncs to your account, or submit your own. Practice on your smart cube with instant feedback: Perfect, Not your alg, Wasted moves, or Likely slip, plus move count and TPS. In no-scramble mode, follow the virtual cube on screen; turn on Continuous to roll straight into the next case. [Favorites & Review] Organize favorites into your own folders, select several to start a Timed, Smart, or Lookahead review, and load any saved or past scramble into any practice mode. Smart Practice also gathers your recent slowest and least efficient solves for focused drilling, judging progress by why each one was picked. [Classic Practice] No smart cube needed: full solving on all six colors (fewest-move Cross, plus XC / XXC / 3XC / 4XC averaging 7 / 9 / 11 / 13 moves), each solution with AI analysis and a 3D demo; plus lookahead practice, real WCA competition scrambles, and step-based Cross training. Records and favorites sync across devices. ## Key features - AI solution analysis with move explanations - 3D demonstrations of algorithms - Automatic review of recent errors - Lookahead prediction and data tracking - Timed practice with cross-device sync - Real WCA scrambles and F2L highlights ## Is XC Master safe?
