HRV4Training

Can’t upload trainings if measurements wasn’t perform. Please correct that

What is wrong with the website? Would be great to access the info after paying for the app...

Gives different results when doing the measurement twice or three times (one by one, without changing body position etc)

Application stopped opening - all I’ve got is just a white screen.

Can’t import my all Apple health data (1 year of measurements).

There are a lot of scientific researches that 5min isn't enough to exactly evaluate your condition. Using only chest strap can guarantee R-R intervals to be typed well. But... This app doesn't allow you to do this🤷‍♂️👍

Looks like very useful tool for multiple analysis(workout,conditioning,etc.) Using for 2 weeks, everything works perfect. Thanks to developers!

Besides its obvious features, I noticed that the developers really strive to polish and improve their app. Many apps rarely receive updates, or just make "cosmetic" changes. I'm using in on day-to-day basis not just to monitor my fitness improvement, but also for self research. For instance, I have a custom tag "mental workload yesterday" to discover how mental stress affects my hrv or hr. I wish there were a way to check hrv several times a day on demand, like in elitehrv, but I understand that the purpose of the app is to get physical response picture. But still)

Not work with new camera.

Last version under iOS 9.2.1 failed to start.
