Great HRVB
I initially gave this app 2 stars because it really wasn’t working and was requiring me to delete data. After communicating with developer. I have re-installed it (including a power down of my phone). I suspect the problem was related to the installation of the latest iOS? I don’t want to get technical about HRV Biofeedback (HRVB) so it suffices to say that this app is great! Furthermore, the fact that the developer communicated with me to solve the problem adds additional value.

Buggy with poor user instructions
The idea of this app really appeals to me.
However, there is a dearth of advice on how to use it - no help section. Furthermore when I did "work it out" if freezes at the section where I should be repeating my daily/ twice-daily journey. The only way I can stop this is by deleting previous data i.e. re-installing the app.
I have recently updated my iOS to 18.0, perhaps the app is not optimised for this?

Don’t change anything. It’s perfect

Too buggy but very promising
Too many bugs (end screen and stats screen)and artifact filtering needs improvement. Very promising concept though. Kudos to the developer.
One of the best, my personal favorite
This is a well thought out app for finding your optimal HRV based on science and individual testing. The testing methodology seems spot on. You can see your stats and learn from them if you so choose. Thus far, if you want to know your optimal HRV, this one is my favorite. I have tried a bunch of them. I now feel that I do not need to keep looking for more “Optimal HRV” apps. Of course I wish it was free, but there was a great amount of time and effort put into the app. Knowing what I know now about it, I would spend the $20 here first, before the other ones I have tried.
