No Longer Relevant
The creator of this app, and other physiology researchers, have proven that the DFA Alpha 1 method of determining aerobic threshold (AT) is deeply flawed and cannot provide a reliable indication of AT.
I wish I had know this before paying for it. Perhaps the author should make this more obvious.

Crashes every time
This is a helpful tool, however this app crashes every time I use it, within half an hour. I’m using one of the HRV4Training recommended bands (Scosche). Renders this otherwise useful tool useless.
Does the app support Fitbit watches?
Hello! Love the app, thank you for developing it! I’ve used it successfully with my polar belt, but it is a bit inconvenient to wear it all the time. Can the app sync with my Fitbit watch? When I try to connect Bluetooth, it doesn’t seem to work.
Export doesn’t work
Worked great until I tried to export my data and none of the 3 options work. Contacted the developer on Twitter but no response. If you are looking to use the app to record your heart rate data for other analysis software then do not purchase until this is fixed.
Loss of functionality
The app inexplicably lost its ability to export files to Dropbox. I’ve tried deleting both Dropbox AND HRV Logger in an effort to make it work again (and lost all my data in the process). Still doesn’t work. Given the limitations of the app itself, exporting the data is critical. This loss of functionality severely handicaps the app.

Cannot upload to drop box
I cannnot upload to Dropbox I’ve tried everything but can’t seem to do it
Disappointing
I bought this to try and use it for the DFA-alpha1 testing of aerobic threshold but have also adopted using it for morning HRV logging. The morning logging is going well but the logging during runs has a fundamental flaw. Twice I have set out with everything running as required, but my phone in my waist belt so not visible to me. On return from the run I find the logger app is sat waiting for me to select the BT HR monitor, as though a drop out occurred at some point. Consequently most of the test run is wasted. My other running app, iSmoothRun, handles this fine since it has a setting to tell it which sensor to use at all times. This logger should do the same, whilst recording, if it has a drop out it should try and pick up the same sensor. Without this I cannot rate the app higher. It was not a cheap app.

Looks like it could be great
I’m re-doing my review bc I had some issues with the user interface and Dropbox, but the developer helped me fix it. It was really an issue on my end.
Things to note:
(1) I did not realise that when I got this, I’d be looking at a spreadsheet of values to help me work out my aerobic threshold level. That’s just where the field is at the moment, so I’m happy to do this, but this app won’t pop out a magic number like an ftp value to stick with for a while. The alpha-1 value is itself dynamic anyway, but I use it on a trainer to get a ball park value that I can implement when riding at Zone 2.
(2) If you do want to go out and ride with this to follow the alpha-1 threshold as you ride, then note you’ll need two sources of HR data (two hr straps) if you use a bike computer, since you’ll now also need your phone to record data. That is, unless your phone can connect to the HR strap at the same time as your bike computer.
(3) This really does require that you pay attention to what you’re doing. It’s not as simple as pedalling and then getting a number. The instructions really do need to be followed.

I would like a refund
I have multiple Garmin HRM straps and the App does not recognize any of them. I don’t want to buy a new strap just to use this App
Interesting data and helps set Aero TH
Used alpha one measurement and exported to a numbers to graph against HR. Interesting to see how it changes when you are not recovered also. Would be nice to see pacing information added to data
