Watchly Our pick
Best overall — watch Prime Video together free with full sync, voice & reactions on every device
Watchly lets you watch Amazon Prime together for free — with full real-time, frame-accurate playback sync so every viewer hits play, pause and skip at the same moment. Prime Video, Netflix, YouTube and SoundCloud co-watching are all free, complete with live reactions, built-in push-to-talk voice chat and live text messages. None of that is locked behind a paywall.
It's built to work everywhere: a native iOS app, a native Android app, and a Chrome extension mean true cross-platform sync, whether you're going phone-to-phone or phone-to-laptop. Just create a room and share a link — friends can join in the browser with no account required to watch along, which makes it ideal for long-distance movie nights across time zones.
Watchly Pro ($4.99/month or $29.99/year, with a 3-day free trial) is optional and only adds extras: no ads, unlimited room members, HBO Max watch-togethers and a Pro badge. Note that Watchly doesn't officially support Disney+ or Crunchyroll. As with every legitimate watch-party app, each viewer needs their own Prime Video (or other streaming) subscription, since Watchly syncs each person's own stream.
