Watchly Our pick
Best overall — free Netflix, Prime, YouTube & SoundCloud co-watch with voice, on real iOS & Android apps
As a watch party app for iPhone (and Android), Watchly stands out because it ships real native iOS and Android apps plus a Chrome extension — so you can host or join phone-to-phone or phone-to-laptop without anyone being chained to a desktop. Watching Netflix, Prime Video, YouTube and SoundCloud together is completely free, with full real-time, frame-accurate playback sync, live reactions, built-in push-to-talk voice chat and live text messages — all free, on mobile and desktop alike. Create a room, share a link, and friends can join right in the browser with no account needed to watch along.
It's built for long distance across time zones, and nothing about the core experience is paywalled — Netflix, Prime, YouTube, SoundCloud, sync, reactions, voice and chat are all free. 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.
To be fair: Watchly officially supports Netflix, Prime Video, YouTube and SoundCloud (and HBO Max on Pro), but not Disney+ or Crunchyroll. And like every legitimate watch-party app, Watchly syncs each person's own stream, so each viewer needs their own subscription to the service you're watching.
Pros

Cons
- HBO Max watch-togethers and extras (no ads, unlimited members, Pro badge) require Watchly Pro
- Each viewer needs their own streaming subscription, since Watchly syncs your own login — true of every legitimate watch-party app
