Before you add it

Your browser will ask to read and change data on your streaming sites, and to show notifications. WatchTandem uses the first to read and control the video player, so everyone stays in sync, and to show the chat beside it. Notifications are only reminders for parties you schedule.

  1. Pin WatchTandem to your toolbar.
  2. Play something on Netflix, HBO Max or Prime Video.
  3. Start a party and send the link.

WatchTandem is free for Chrome, Edge and Firefox on a computer, with no account. Send this page to yours.

Show a moment in a party

When someone hits an ad, the party waits for them, shows who and for how long, then everyone resumes together. Verified live on Prime Video’s ad-supported plan.

Free voice and video calls for up to 6, right beside the show. Each voice has its own volume, and the show gets quieter while friends talk.

Can’t agree on what’s next? Start a poll, or add titles to Up next and vote. The host plays the winner for everyone.

Schedule a night up to two weeks ahead and add it to Google, Apple or Outlook calendars. Everyone gets a reminder 10 minutes before, then you start together with a 3, 2, 1 countdown.

Everyone sees the same moment, and the sidebar says how close in plain words, with each person’s drift. About 21 ms apart on Prime Video, measured on 7 October 2026.

A preview of WatchTandem’s sidebar beside an episode of Night Shift, a made-up show: a quiet street at night with a lone rider under the street lamps. The buttons above switch between five moments: the party waiting for Leo’s 20-second ad break, a video call with four friends, a poll and the Up next queue, a party scheduled for Saturday at 8 PM, and each person’s sync drift.

Everyone watches with their own subscription. WatchTandem never streams, records or shares video.

Ads don’t break the party.

On ad-supported plans, ad breaks land at different times for different people. WatchTandem waits for whoever is in one, shows who and for how long, then everyone resumes together.
