Time your cube solves
Scramble, solve, stop — then watch best, mean, Ao5, and Ao12 update. Practice-grade scrambles and WCA-style averages.

The job
A speedcube timer does three things: shows a scramble, times the solve, and keeps statistics. Ao5 and Ao12 (drop best and worst, average the rest) smooth single lucky and unlucky solves into a truer level.
Scramble, start, stop
Apply the displayed scramble, tap start, solve, tap stop. The time lands in the session list; best/mean/Ao5/Ao12 refresh each solve.
Worked example
Five solves of 12.00, 9.80, 15.40, 11.00, 13.20 s: best is 9.80 s, mean 12.28 s, and Ao5 drops the 9.80 and the 15.40 to average the middle three — 12.07 s.
Scope
21-move random scrambles that avoid consecutive same-face turns — good practice scrambles, but not state-generated like official WCA scrambles. Up to 500 solves are kept in the tab; nothing is saved between visits.
