and the app is kinda cool.

It does track your heart rate, but the measurement seems a bit low (on mine at least). Works okay for telling if your heartrate increases or decreases so if you can match a reading with your target zone you can use it to maintain a target heartrate (though the exact bpm of your target heartrate might not be perfectly correct). It's got a pedometer too which works okay, and the app is kinda cool.
