Overview

A room where you and your friends watch YouTube in sync, with chat, floating reactions and a queue anyone can add to.A room where you and your friends watch YouTube in sync, with chat, floating reactions and a queue anyone can add to.

The challenge

Watching something together on a call means a “3, 2, 1, play” countdown, and five minutes later you’re out of sync again. On top of that, most watch-party apps want everyone to sign up first.Watching something together on a call means a “3, 2, 1, play” countdown, and five minutes later you’re out of sync again.

The approach

No accounts. One tap makes a room with a short code, and friends join from a link. Play, pause and skip happen on everyone’s screen, anyone who falls behind gets caught up quietly, reactions float over the video, and the next thing in the queue plays on its own.No accounts.

Cinema Date NightCinema Date Night

Buddies takes Cinema Date Night and turns it into a whole brand: a logo of two speech bubbles around a play button, an app icon that still works at 16px, sample thumbnails and a set of reactions. The colours got new jobs for a group. Rose is what you do, merlot means the room is in sync, butter means someone’s here right now. A watch party should feel like a sofa, not a control panel.Buddies takes Cinema Date Night and turns it into a whole brand: a logo of two speech bubbles around a play button, an app icon that still works at 16px, sample thumbnails and a set of reactions.
