An iPhone is many things, but a massage therapist it is not. However, if you're in a pinch, the lightweight app Massager may sooth you until your next appointment. The app takes advantage of the iPhone's vibrating motor to create four patterns based on Swedish, Shiatsu, deep muscle, and relaxation massage. Starting and stopping the massage are easy enough to accomplish by tapping and untapping the button. While you can manually increase the intensity by putting some muscle behind the iPhone's flat face, it doesn't even come close to what a pronged massager can do. Yet it might relax tension in you and yours, and at 99 cents, that's not a bad investment.
