Suunto’s Smart Belt is the smallest Bluetooth-Smart-compatible heart-rate monitor on the market, but that doesn’t mean it’s less functional than other devices. It transmits heart-rate data from swimming, running, cycling, and other sports to your device of choice and, using the free Suunto Movescount app, you can analyze your workouts to see how much fitter you’re getting.
