Compatible Heart Rate Monitors
CorSense by Elite HRV
The CorSense® HRV monitor was specially designed by Elite HRV to capture accurate heart rate variability in a convenient finger sensor.
The Polar H10 chest strap HR monitor is Polar’s newest and most accurate heart rate sensor.
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).
- CorSense HRV finger monitor
- Polar H7 or H10
- Wahoo TICKR – Only Bluetooth is HRV accurate, ANT+ is just HR accurate
- BlueLeza HRM Blue – Only available in Europe
- 4iiii Viiiiva
- Zephyr HxM (make sure it’s Bluetooth 4.0, not 2.0!)
- Cardiosport TP3
- Suunto Smart Belt
ANT+ only (not compatible with iPhone or iPad)

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 the 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 HRV monitor 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.
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.
