Pulse Rate: Blood is constantly moving through the human body and consequently the amount of blood under the skin at any given point is constantly changing. The main forces of blood movement are the heart pumping and physical body movements. The Scosche RHYTHM armband detects blood movement by shining light onto the skin and measuring the amount of light that is absorbed by the skin. In addition RHYTHM uses an accelerometer similar to what is used in popular gaming controllers to detect body movement and then subtracts the movement from the light measurement. All of the data collected from this process is wirelessly sent to your Apple iOS or Android device for further filtering and signal processing via Bluetooth. The final output is then displayed on your Apple iOS or Android device's LCD screen as your pulse rate.

Calorie Counter: Calories burned are calculated using your weight, pulse rate, and time elapsed. Be sure to enter your specific settings prior to beginning a workout.

Training Zones: Your max heart rate is based on the standardized formula; 220 minus your age equals your max heart rate. Each training zone represents a percentage of your max heart rate: Resting 40-59%, Weight Loss 60-69%, Fitness 70-79% Performance 80-89%, Red Line 90% and above.

Partner Apps: You can also use the RHYTHM armband pulse monitor during your workout with the following partner apps - Digifit, iBiker, iPower, RunDouble C25k, iSpinner, iCardio, iRunner, iSmoothRun, Spinning, Runkeeper, MapMyFITNESS, and MyFitnesPal.
