Every once in a while, you’d like to have a timelapse video that suddenly does something else. Maybe a bird flew dangerously close to a friend, or somebody was giving you a hilarious stink-eye as they walked by. If that’s ever been your experience, you’re probably left taking to a desktop movie editing app to get the results you want. Now you don’t have to. A new iOS app named Tempo is here to bring you easy video editing based on the speed you want your video to play.
