Speedrun: a pro split timer, built in

The Speedrun page gives you a pro split timer without any extra tools.

Pick a game, press Launch and the game starts with the timer ready to go. Your hotkeys handle splits, pause and reset while you play, and the run clock shows your time against your best.

Your personal best and sum of best are always on screen. Look back at your run history, record your runs, and see where you stand on the leaderboards.
