Watchly Our pick
Best overall for Mac — native app, true cross-platform sync
Watchly is a native Mac app (download from the Mac App Store, runs on Apple-silicon Macs) built specifically to watch movies, shows and videos together in real-time sync. Everyone presses play at the same instant, and playback stays locked no matter who pauses or skips. Because it is native rather than a browser tab, it feels faster and steadier than the web tools below.
Its real edge is cross-platform sync: your friend on an iPhone or Android phone can join the same room as your Mac, and a browser guest can hop in from the shared room link with no account needed. Co-watching is free on Netflix, Prime Video, YouTube, Hulu and SoundCloud. Watchly Pro ($4.99/month or $29.99/year, 3-day free trial) unlocks HBO Max, Disney+, Crunchyroll, Peacock, Paramount+, Apple TV+, Plex, Tubi and more, plus unlimited room members and no ads.
Built-in push-to-talk voice chat, live reactions and text messages mean you never need a second app for a video call on the side.
