Users capture four-second bursts of video by covering a sensor directly above the earpiece of the iPhone. During an interview in his Manhattan office on Thursday, Mr. Neistat demonstrated this by pressing the phone to his chest — a similar motion, for instance, to holding his hand over his heart as if he were singing the national anthem. The phone beeps and vibrates to let you know it is recording, and does so again when it has finished.
We were playing around with the app this morning at Coalwork. It is pretty great. Looking forward to seeing how it evolves.
