HRV +

No annoying accounts or anything, does what it's supposed to.

Iphone se/ ios13.3

I’ve been searching for an HRV app like this for a long time with no success. This is exactly what I was looking for. All I wanted to do was to use my Polar H10 heart rate strap to measure my HRV and HR while I am sleeping. I don’t want any pep talks or recovery scores or anything like that, just the data — average HR, average HRV, average RMSSD. This is perfect! Thank you so much to the developer for creating this app. I’m not able to contact the developer here but my question is, I assume the HRV metric shown above RMSSD is SDNN?

I downloaded this app a while back and never worked

I cannot connect my Polar H7 using iPhone 6 / iOS 8.4. This is my first attempt, so I don’t know if it worked on older iOS. I *can* connect my H7 to other apps, so it appears to be an issue with HRV+. I hope the issue is resolved, as I would like to try this app.

I have a Polar H7, which all my other heart rate apps seem to have no trouble with. This app can’t see it for some weird reason. The “info” says to “wet the sensors”. Well, I’m not rolling out of the rack to drop a bunch of cold water all over my chest, thanks. It’s a shame, the GUI is awesome but the product just doesn’t work.

HRV+ Connected on the first try with my Jarv BT monitor. Get your music or podcast app running first, then start HRV and you can listen while you work out and monitor your heart rate. A nice enhancement would be to plot an exercise session by the second.

Won't connect to HR7 monitor.

Purchased the H7 after reviews stated it would work on iPhone. Does not recognize device. Please update.

Used it a lot, no complaints, but after getting iOS 8 it no longer connects to my polar h7. RunKeeper still connects to it though, so it's not a phone issue.
