Vidrip is a free app for iPhone and Android. Send a video to a friend, they watch it on their own phone while Vidrip records their reaction, and you get the reaction back synced side by side with the original video. Built by Vidrip, LLC, a small independent studio in the US.
We built Vidrip because the best part of sending a friend a funny video is seeing their face when they watch it, and you're never there for it. Vidrip fixes that: you send a video, your friend watches it while their reaction is recorded, and you get the reaction back synced with the original.
