Slow-motion videoThe iPhone 5s lets you record slow-motion video. The SlowCam app on your iPhone 5 brings the super-smooth slow motion video capture from the iPhone 5s. Pressing and holding the Slow Motion button right above the record button lets you record the video in slow motion.
The iPhone 5s can record 120 fps, making this a fine replacement for Apple's stock camera app. The iPhone 5 can pull down 60 fps, but the iPhone 4 and 4s can only reach 30 fps.
