BreathTuner HRV for Android

I paid for this app and was able to see my data to compare brpm. After a phone reset I suddenly can’t access the measurements I take and I am prompted to pay again (and that after investing in their other app as well). Disappointed!

I bought the pro version and found my resonance frequency to be 5.75 br/min. I really like that you can do the narrow tests to pinpoint resonance frequency. What I would like for in an update are: 1. In the “Breathe” practice part, it would be nice if I could set the rate to 5.75. Currently, you can only set it to 5.7 or 5.8. What is the point of pinning down the breathing rate in detail if the app can’t help you practice at that rate. 2. Also in the “Breathe” part, it would be nice to have a timer so I don’t have to use an external timer to time a session. Other than that, the app is great!

I saw your response about why you cannot support the H9 polar sensor so I bought an H 10, and I bought the pro version of this app. The one problem is that the measurement feature does not seem to be working for me. I’ve connected my heart rate monitor, and when I start the measurement it says collecting heart rate data or something like that. And it has a picture instruction, telling me to tuck my phone into my waist band. But even after I took my phone into my waist band, and I’m doing abdominal breathing for several minutes, that helps screen never goes away, and I never get any verbal instructions on what to do. Just continuously shows that image that tells me to put the Android in my waist band. I have double checked that I’m doing it right according to the instructions. I have the phone upside down, charging port facing up, the displays facing out, the phone is talked about halfway into my waist band, and it is rising and falling with my breathing. Please let me know if I’m doing something wrong or perhaps if there is a bug with the app or if there’s anything I can send you to help you diagnose the problem. I’ll also reach out via email.
