I have no idea what these numbers mean, and there’s no explanation. You have to think like a user and not purely like a scientist when you give people apps.

I like this but when I start it, live track starts too. Can this be turned off?

I've tried a few HRV apps on my VivoActive 4, and this one is very user friendly, however for some reason, when I use this, Connect always displays my respiration as 4 breaths per minute. (I tend to rest at 10 breaths per minute... I've counted while using this app!) Am I doing something wrong, or is this a bug?

The app works great on forerunner 645… thanks a lot!

Works great on my Forerunner 245. I would suggest an improvement. In Garmin Connect it shows the activity "Test HRV" and shows breathe and heart rate. I would like to select a HRV measure there, e.g. RMSSD. Then I would not have to open each activity

The app works great on my 935. Will you make it available on the Forerunner 955 as well? I would even pay for it! Thanks!

Very good and accurate HRV app, best I have found for Fenix. You need to use a HR Chest strap but that’s the only way you can get any accurate HRV reading. Have compared it to 2 highly rated Apple iOS apps, they also use a HR Chest strap. Test HRV app reading match, only Garmin app I’ve found that does.

App is okay but doesn’t provide all that is advertised. 1) advertises 8 HRV statistics... only provides 4 2) advertises extra graphs but they are not available Additionally, the app does not provide any means for long term tracking analysis.

Hey, great app thank you. Quick question, I've noticed my body battery drops significantly like 5 points right after running the app which is weird because I often run it at rest to test my HRV. Is there an explanation to this phenomenon ?

V Good app thanks In my Garmin 945 watch same HRV STRESS but requires HR chest strap . Results are different ? in this app wrist watch is enough or needs the HR chest strap ?

Good application. I would like the option to edit the live track. Every time I start this it sends messages to my live track followers. They don't need to know this and I should be able to turn it off for this.

I have a vivoactive3 and so far the app is on my watch but it doesn't seem to load when I select it. It is strange. It greys out when I select it but never loads.

Thank you. The app is great and easy to use. I would appreciate if you could add a choice to save or discard the activity upon completion of the measurement. Right now it saves it all the time automatically which leads to upload to GC, Strava etc. I need to manually delete it if I do more measurements.

excellant app...quick and reliable...some sort of history would be a a great addition...

Well done. And forget those who blame you for not explaining something to them they got for free.

Great app. It's easy to use and I recommend it to those who want to estimate their HRV.

Should support the HR belt and Edge bike computers. What to do so that the HRV test does not automatically send to strava :)
