Creating short reels out of GoPro footage requires video editing knowledge, that's why some casual users don't even bother. Well, that could change soon enough -- or at least as soon as the company's new mobile app launches. According to TechCrunch, GoPro president Tony Bates has revealed to investors that the action camera maker is developing an app, which will give users the capability to edit and trim footage straight from a phone or tablet. It's in the final testing phase and could be out by the end of summer, so don't be surprised if you find your News Feed filled with friends' surfing, swimming or hiking videos.
