Compatible Heart Rate Monitor Straps

Requirements for Compatibility

To accurately measure Heart Rate Variability and transmit it to your compatible phone or tablet the strap must have:

  • Bluetooth 4.0 (also called Smart or LE)
  • Accurate R-R Interval Recording (also called inter-beat intervals)

The manufacturer should be able to tell you if their device meets these criteria. If they don’t understand your question, run!

Recommended Heart Rate Strap

We currently recommend the Wahoo TICKR series or the Polar H7. It is compatible with many apps (not just ours) and has performed well in our rigorous testing. To get the best deal on a Polar H7 check them out here.

Other Compatible Straps

Any heart rate chest strap that accurately measures R-R intervals and has Bluetooth 4.0 should work. Here are a few more that have been proven to work well with Elite HRV:

Not Compatible Devices

The following have been tested and do not provide accurate R-R intervals via BT 4.0, thus are not compatible:

  • TomTom BLE HRM
  • Mio ALPHA
  • Scosche RHYTHM+
  • Apple Watch
  • Fitbit Charge HR
  • Most cheap chest straps sold on Alibaba
  • Knock off monitors
Wrist Bands, Watches and Other HR Devices

True Heart Rate Variability calculations require accurate measurement of the time between each heart beat. Unfortunately, wrist bands and watches that use LED/Pulse Oximetry type sensors are not accurate enough yet. For accuracy and multi use purposes we strongly recommend the Polar H7 or similar Heart Rate Strap. 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.

Compatible Phones and Tablets

  • iPhone 4s, 5, 5c, 5s, 6, 6S, 6 plus, and newer
  • iPad 3rd generation, 4th generatoin, Air, Air 2, Mini, Mini 2, Mini 3, and newer

How to check which Apple device you have:


Your device not listed here?

If you are not sure about the above information, your device’s manufacturer should easily be able to tell you if your device uses Bluetooth 4.0 and/or measures RR intervals. If they can’t, 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 RR intervals? Also, does it have Bluetooth 4.0 capability?” – make sure to tell them what heart rate monitor you have.
