CompSim

CompSim is your ultimate competitive speedcubing timer. In an official cubing competition, you don't do individual solves⁠⁠—you solve in an average of 5, mean of 3, or best of 3 format. CompSim streamlines this mode of practice by giving you the capability to practice like this and visualize your progress from this perspective.
Not only that, but CompSim allows for you to set a target, or a time to beat. This allows you to work toward a certain goal, like your official personal best (PB) or your long-term barrier. 
When you win (or lose), you get to the experience acted out by a cuber of your choice!
CompSim has plenty of customizable, intuitive features to make the user experience better than any other cubing timer, period. From WCA inspection and timer update to custom holding time and a beautiful dark mode, you can make your CompSim experience unique to you.
Of course, CompSim comes with the standard capabilities of any cubing timer⁠⁠—scrambles of all types, on-screen timing to the nearest 0.01, stackmat timer entry, and penalties are all included through a beautiful interface.
