Livesplit is the de facto standard timing software for speedrunning. It displays a running timer alongside 'splits' (checkpoints that show your time at specific points in the run compared to your personal best or a target time). Splits glow green when you're ahead of pace, red when behind, and gold when you set a segment best. The tool also supports auto-splitters, plugins that read game memory to automatically trigger splits at specific events, removing the need to manually press a hotkey. For runners, Livesplit is more than a timer: it's a training tool that identifies weak segments, tracks improvement over time, and provides the real-time feedback that drives the 'one more attempt' mentality.
