hi! I'm planning on becoming a new speed runner(probably just speed running web games) and I'm on a personal chromebook but I don't know what timer to use! I don't know how to download livesplit on Chromebook, I was planning on using livesplit one but idk how to use that either. can anyone help me download livesplit on chromebook or help me set up live split one? or if you know any other timers that are good for Chromebook it would be greatly appreciated.

There are several livesplit video tutorials, including English and Spanish on the github. If it's a popular game, there should be a livesplit to download on the speedrun page.

Really, you don't need to use any timer to get started. Can eyeball the time to the whole second and submit. Mods will retime if need be. I've used my phone's stopwatch with Auto-Lock set to never to pace myself. There are tutorials for how to add a timer in OBS. I've added a timer while video editing to nail start and end to the exact frames but that's completely unnecessary.
