The most convenient way to measure heart rate variability!

How does the ithlete Finger Sensor work?

The ithlete HRV finger sensor works in the same way as the pulse monitors often seen in hospital emergency departments.

An infra-red light is sent through the tip of the finger with a sensor on the other side which measures changes in the amount of light received. As the heart beats blood is sent around the body, with each beat the blood density is the finger changes and it is these changes that are recorded by the finger sensor.

As with all ithlete heart rate variability measurements this information is processed to present you with a daily HRV number and personalised training recommendations.


  • Simplicity & convenience of measurement
  • Durable and portable the ithlete Finger Sensor is perfect for travel
  • No battery required
  • High quality
  • Scientifically validated


The ithlete HRV Finger Sensor is compatible with the following devices:

  • iPhone 3GS & above
  • iPod Touch 3rd Generation & above
  • iPad & iPad mini

  • HTC One

The ithlete Finger Sensor is designed specifically for use with the ithlete HRV app and is not compatible with any other apps at this time.

Please Note

The ithlete finger sensor has been tested on hundreds of people, and works fine in the vast majority of cases. However people with poor circulation in their fingers, low blood pressure, or who are wearing thick nail varnish may experience problems and are advised to choose another sensor type, such as a chest strap. We also don't recommend the ithlete finger sensor for children, due to the small size of their fingers.
