Use the randomly generated scramble on your cube, or scramble it yourself if you do not know the notation. When ready press space to start inspection. When the inspection is done, then the timer will start. Press space to end the timer. Sorry for a scramble that his things like "M' M" or "R2 R2". Try to beat My personal record of 11.64!
I used PTE ultra made by ~Rex~ for the timer.
