Slow Fast Slow from Studio Neat

Our friends at Studio Neat have just released their latest thing: an app for shooting in slow-motion at 60 frames per second (fps) on an iPhone 5/5c or fifth-generation iPod touch and 120 fps on the iPhone 5s. While SloMo at 120 fps is a mode on the iPhone 5s, it doesn't offer much control nor does it adjust pitch to normal. Slow Fast Slow can also reduce speed to 1/8th normal, twice as slow (or is it half as fast?) as the iPhone 5s SloMo mode. It's a buck-ninety-nine.
