Watchly Our pick
Frame-accurate sync on phones and laptops, with voice built in
Watchly is built around one idea most rivals skip: people watch on their phones. It ships as a native iOS app, a native Android app and a Chrome extension, and all three join the same synchronized room. The host shares a link, friends tap to join, and play, pause and seek stay locked for everyone at once.
The free tier is genuinely usable: full sync, push-to-talk voice chat, live reactions and text chat, plus the free services YouTube, Prime Video, Netflix, SoundCloud and Hulu. Watchly Pro ($4.99/mo or $29.99/yr, 3-day free trial) removes ads, lifts the member cap and unlocks services like HBO Max, Disney+, Twitch, Crunchyroll and more. Each viewer signs in with their own streaming subscription.
