Sync-Squad Watch Parties

Watch on your TV. React on your phone. Drop reaction pins at exact timestamps ("EPIC FIGHT," "CRYING," "PLOT TWIST") and see a heatmap of where your squad lost it. Voice chat with expressive anime avatars that react when you yell at the screen.

Anime fandom deserves its own home

Not a subreddit. Not a Discord server. Not a browser extension. A purpose-built place where watching, creating, and belonging happen together.
