Trying to watch movies long distance is frustrating when streams keep lagging. We always had to do the "3, 2, 1" countdown and it never synced right. So, I coded CoupleMode to fix it. You just paste a YouTube link and it syncs perfectly in HD for both of you without any extensions. I also added a leveling system so you earn XP while watching together, and a floating chat so you can text without pausing the video. Built this to solve my own problem, hope it helps you out too!
