Requirements for Compatibility

To accurately measure Heart Rate Variability, your heart rate monitor of choice must:

  • Capture and transmit accurate R-R Intervals (also called Inter-beat Intervals or IBIs)
  • Transmit the unaltered R-R intervals via Bluetooth 4.0 or ANT+ (ANT+ receiving only available on certain mobile devices)

Compatible Heart Rate Monitors

The app is compatible with any heart rate monitor that accurately measures R-R intervals and has Bluetooth 4.0 or ANT+ (ANT+ only available for Android devices – see why ANT+ is not available for iOS here). Here are a few that have been proven to work well with the Elite HRV app:

Recommended heart rate monitors:

         Polar H10 Elite HRV .     Polar H7 Elite HRV

      

Other compatible monitors:

ANT+ only (not compatible with iPhone or iPad)

These are compatible with many apps (not just ours) and have performed well in our testing.

Not Compatible Heart Rate Monitors

The following monitors do not transmit accurate R-R intervals, thus are not able to be used for measuring HRV. However, in most cases, they are fine for measuring basic heart rate.

  • Wahoo BLUEHR*
  • Wahoo TICKR FIT Heart Rate Armband*
  • Polar OH1 Armband*
  • Vernier Go Wireless Heart Rate*
  • Geonaute*
  • MyZone MZ-3*
  • UnderArmour UA Heart Rate*
  • LifeBEAM hats
  • TomTom BLE HRM*
  • Mio ALPHA
  • Scosche RHYTHM+*
  • Fitbit Charge HR*
  • Lezyne HRM
  • Most cheap chest straps sold on Alibaba
  • Knock off brand monitors

*Confirmed by the manufacturer

The following HR monitors are not open to 3rd-party platforms and therefore are not compatible for use with Elite HRV at this time.

  • Whoop wrist device
  • iThlete Finger Sensor
  • Heartmath devices
  • Oura ring

About PPG (Photoplethysmogram) and Pulse Oximetry Devices

True Heart Rate Variability calculations require accurate measurement of the time between each heart beat. Unfortunately, most wrist bands and watches that use LED/Pulse Oximetry type sensors are not accurate enough yet to capture the exact R-wave peak. Technology has advanced to where these devices can accurately measure basic heart rate now, but that is because heart rate is not sensitive to tiny changes the way that HRV is.

As an example: If your heart rate is 60 beats per minute, your heart could be beating once per second. In this case, if you were measuring the time between each beat in seconds, it would be 1s, 1s, 1s, 1s, 1s. OR… Your heart could be alternating speeds – something like: 1.17, 0.97, 0.83, 1.03. Either way, your basic heart rate could still be 60 beats per minute. But your heart rate variability would be significantly different in these two scenarios.

Many devices aren’t built to measure HRV, so they simply smooth out, or average, the R-R intervals to make it easier to report basic heart rate.

For accuracy and versatility, we strongly recommend the CorSense or a compatible heart rate chest strap listed above. We are continuously researching the application of wrist HR monitors, pulse oximetry, finger sensor, ear clip and other options. When we are satisfied with accuracy and quality of these devices, we will let you know.

Since the chest strap requires conductivity to capture heart rate and HRV data, it is best to wet it with water or conductive gel. Some users report that conductive gel provides a much more reliable signal for their body type or environment. Here is an example of conductive gel.

Your device not listed here?

Due to the large number of devices on the market, we are unable to test them all for accuracy and compatibility.

If you are not sure about the above information, your device’s manufacturer should easily be able to tell you if their device meets the criteria for compatibility. If they can’t, then we would recommend not doing business with them. Look for the contact form on your device manufacturer’s website. Here is how to find out if your device is compatible:

Phone or Tablet Send a message to your phone or tablet’s manufacturer asking, “Does this device receive Bluetooth 4.0 signals?” – make sure to tell them what device and version you have.

Heart Rate Monitor Send a message to your heart rate monitor’s manufacturer asking, “Does this heart rate monitor capture accurate RR intervals? If so, does it alter or smooth the R-R intervals in any way? Also, does it have Bluetooth 4.0 capability?” – make sure to tell them what heart rate monitor you have.
