FourShot
FourShot records your scene and you at the same time with the iPhone's back and front cameras, and saves four videos from one take: the scene and your reaction, each in vertical (9:16) and horizontal (16:9). Live beauty and looks on your camera, filters on both, 1080p at 30 fps.
Free: every feature, takes up to one minute.
FourShot Pro: unlimited recording length. Try everything free for 3 days, no card needed. Then monthly, yearly or a one-time lifetime purchase.
Needs an iPhone that can record the front and back cameras at the same time (iPhone XS, XR or newer) with iOS 17 or later. Videos never leave your phone.
