1. Note: If you cannot connect your Bluetooth Smart heart rate monitor, make sure that is not paired already with another application or device.
2. To use the application you need an heart rate monitor that adheres either to the Bluetooth Low Energy or ANT+ standards.
3. We have personally tested the application with the Viiiva, Garmin, Wahoo and Polar Bluetooth Low Energy heart rate monitors.
4. The Bluetooth standard does not allow to have the heart rate monitor connected at the same time to multiple apps or devices.
5. The SelfLoops HRV application calculates and displays the heart rate variability.
6. Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats.
7. Also, do not pair the heart rate monitor in the Settings of your device.
8. By using the application you expressly agree that SelfLoops is not providing medical advice with this application.
9. If you record the session you will be able to export the data, saved in csv format, to Dropbox, Google Drive, by email etc.
10. This application is used by pro athletes and olympians.
11. There are several metrics used in the scientific literature, we calculate: SDNN, RMSSD, pNN50, AVNN.
1. Works great with Polar H10.Not sure what is going on here my Polar a370 connects and displays HR but not RR or anything else shows up and the data is blank when I export it? Is this app a dud?Paired with a magene....I like it so far seems easy acurate and simple to use.
2. I connected one Rhythm24 band with the app, and although one band connected and HR and HRV RR intervals data was displayed, other Rhythm24 bands that I connect to the same app was not displaying any HRV data, just the HR data.
3. Thanks selfloop!App has very hard time if any other app has hooked up to polar h10 monitor which means I have to restart phone to take a reading big pain in the ass.
4. If you can help me understand why that's the case, perhaps I can rate the app higher because it's not a bad app after all.Only one I found, which has unlimited recording plus export.
5. Selfloop allows me Unlimited recording of my hr and hrv data.
6. Pls add some prognostic & diagnostic abilities.Doesn't connect to Kardia EKG or Fitbit Versa.
7. Both work on Bluetooth.Another app won't send clarification code ! Uninstalling !This is just what I've been looking for.
8. None of my other fitness apps have this problemIt monitors rr timing well.
9. ThanksEasy to use and great connectivity.
10. I used to use "camera hrv" but it only recorded and analysed one minute of hrv.
11. Recording the values.
