Free. No ads while you solve: never over the timer during a solve. Available in Spanish, English, Portuguese (BR) and German.

WCA timer

Scrambles and images for every event (3x3, 2x2, 4x4–7x7, Pyraminx, Skewb, Megaminx, Square-1, Clock), 15-second inspection with voice alerts and +2 / DNF penalties.

FREE

Statistics

ao5, ao12, PB, full history, heatmap and phase breakdown (Cross, F2L, OLL, PLL).

FREE

Algorithm library

Full CFOP (OLL, PLL, F2L), 2x2 (Ortega, CLL, EG), Roux, COLL, notation and patterns, with recognizers to train the see-to-execute step.

Performance analysis

Turns your solves into signals about your execution —consistency, smoothness, recovery, phase reading— computed on your own data.

PRO

Honest about what it does (and doesn't)

Kruxmind measures your cube-solving performance. It is not a medical device, it does not measure brain activity, and it does not claim to improve your intelligence or prevent any condition. Training the cube mostly improves what's closest: the cube itself and skills tightly linked to it. Review the references and their limits in the Scientific basis.
