JumpCam - Record Videos Together with Group Video Camera is all about recording videos together with a group video camera. For some reason I feel like you knew that already.
Anyway, users can film short video clips and invite their friends to add more to it. The app will then combine the short video clips into one movie with no need for editing. Users can add filters and music to give it more style, though, so editing still exists for those who wish to do a bit more to their videos. Check it out!
