Heart Rate Variability Logger App Reviews

Update V4.6.8 Working on iPad. Thank you for the iPad update, have made and saved several measurements. Sensor selection is appreciated. I will check your web site to get more information on the “Workout” correction factor. More aggressive at higher heart rate makes sense but I would like to understand the details better. The addition of DFA alpha1 is quite interesting. I will have to do some research as I have not used this feature in the past. HRV Logger is a great tool for monitoring performance over longer periods of time. Thank You.

Best serious HRV app. This app is not a simple "show me my stress levels" app (use HRV4Training for that). It will record full HRV details and upload them to dropbox for more detailed analysis.

Falla. La aplicación no funciona correctamente. El problema que tiene es que se apaga sólo. Es indispensable que reparen ese problema. No entiendo como el App Store permitió subir una aplicación que no funciona correctamente : ( Terrible

Doesn’t work. I just bought the app and it doesn’t work, I would like to have a refund!

Works great!. I use HRV4Training (same developer) daily and recommend it to all the athletes that I coach, as it is the best HRV app I've used. I purchased the HRV logging app for extended data analysis, and it works great. I sync'd directly to my Dropbox account (creating CSV files), allowing me quickly import the data into Excel. It has been extremely useful in allowing me to capture HR irregularities (PAC/PVCs), while working, sleeping, exercising or even sitting at my desk (with Bluetooth HR strap). A very effective logging tool!

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.

Lots of potential. Have been using the app for a couple days now to log my heart rate from my Alpha Mio. I think it's going to be very helpful in looking at my dysautonomia. Sometimes my HR is recording then is suddenly stopped- if this bug was fixed if give the app a 4 at least. Excited to see the possibilities with it.

Needs work. Export to dropbox did not work.

This app doesn't work. Will not connect with my new Polar Bluetooth Transmitter that works fine with ithlete & Sweet Beat. Just wasted $4.99 on crap!

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.

Finally a no BS app.. Bloated apps can be infinitely frustrating for data collection and analysis. This app gives you straightforward data collection and analysis with a simple user interface. I will probably purchase other developer apps individually just to support him. Nice to see an app that doesn't try to exploit human weaknesses/impulses or cater everyone at once. 🤗

Outstanding app. Can you make a pebble app or add a companion pebble watchface to this one? I'm sure you are already thinking of the apple watch as well.

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

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.

Crashes and No Refund. Bought the app, crashes hard. Never worked, not updated in years, Apple and the greedy developer refused my request for a refund. Stay away!

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

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.

Excellent heart rate monitor. I use these recordings during atrial fibrillation events to better understand what is happening and give the treating Dr a picture of the duration and range of my HR. The rr values and interpretations of this data are essential to determine the difference between a normal rapid heart rate and the anomalies associated with AF

Not useful for novice HRV trackers. I bought this app believing it can help me track my physical stress levels in realtime. However since it only provides technical data intelligible to people with a novice understanding of how HRV works, this app isn't useful and sadly for me it was $12.99 wasted.
