WatchStats – YouTube & Twitch Watch Time - Track your YouTube & Twitch watch time and habits.

WatchStats is a Chrome extension for people who want to know where their YouTube and Twitch time actually goes. It tracks real foreground watch time — not just how long a tab stays open — and turns it into daily and weekly stats, viewing patterns, top creators, streaks, achievements and a searchable activity history. You can use it without an account, or optionally sync your history across devices, add friends and compare the stats you choose to share. Free, no ads.
