1. A method of determining a user'"'"'s heart rate using a worn biometric monitoring device comprising a plurality of sensors including a heartbeat waveform sensor and a motion detecting sensor, the method comprising:

  • (a) collecting concurrent output data from the heartbeat waveform sensor and output data from the motion detecting sensor, wherein the output data from the heartbeat waveform sensor provides information about the user'"'"'s heart rate and wherein the output data from the motion detecting sensor provides information about the user'"'"'s periodic physical movements other than heartbeats;

    (b) determining a periodic component of the output data from the motion detecting sensor;

    (c) processing the output data from the heartbeat waveform sensor to remove the periodic component from the output data from the heartbeat waveform sensor;

    (d) using the output data from the motion detecting sensor, determining a range of expected heart rates;

    (e) determining the user'"'"'s heart rate from the output data produced in (c), wherein the determined heart rate exists within the range of expected heart rates; and

    (f) presenting the user'"'"'s heart rate.
