Watchly Our pick
Best overall for Mac — native app with true cross-platform anime sync.
Watchly is a native Mac App Store app built for exactly this: watching anime with friends online in perfect real-time sync. Everyone signs into their own streaming account, and Watchly syncs every play, pause and seek so the whole room stays on the same frame. It is genuinely cross-platform, so your friend on an iPhone and your cousin on Android join the same room as your Mac.
Anime on Netflix, Prime Video, Hulu, YouTube and SoundCloud is free to co-watch. Crunchyroll requires Watchly Pro ($4.99/month or $29.99/year, with a 3-day free trial), which also unlocks Disney+, HBO Max, Peacock and more, removes ads, and lifts the room member cap. Built-in push-to-talk voice chat, live reactions and text messages come included, so you can scream at the plot twist together in real time.
