SameSecond от Kerry

SameSecond keeps your group on the same second of the same episode.

Open an episode, click SameSecond and start a room. Send the invite link to your friends. When anyone presses play, pause or skips ahead, everyone's player follows within a fraction of a second.

Unlike screen-sharing watch parties, nothing is re-streamed. Everyone plays the video on their own device at full quality, signed in to their own account, so there's no lag and no blurry picture.

• Works on Netflix, YouTube, Crunchyroll and most sites with a video player
• Chat and voice chat built in
• Follows the host to the next episode automatically
• Waits for anyone whose video is still loading
• The host can choose who controls playback
• Friends on phones can join YouTube and video-link rooms from the invite link, and chat and talk in any room
• No account, no ads, free and open source

Everyone in the room needs their own access to the site you're watching.
