On the Cut is a free app for videoing on the iPhone.
A quick test video:
It is so simple to use. Keep in contact with the screen to video, let go to pause, retouch to continue with the same video. Any time you are not touching the screen the video can be saved to the camera roll or deleted.
The video is a square format (480x480 pixels) mp4. Keep the camera upright, portrait orientation, or the video comes out sideways as I found out and had to get Youtube to rotate the above video.
