It is great application for HRV measurement. thank you for it. But I notice that if a person having one or more ectopic beats, the rmssd will become unreliable will any alogorithm solve this problem in the coming new version? Thank again

Summary: Wow! Stellar application! All details I could ask for plus graphs, trends, initial classifications derived from parent population (so you get an idea to classify the results until you have established your baseline). Very extensive customizability (via Connect IQ and settings directly on the watch). Those settings include technical (such as the timer time that you can reduce here, defaulting to 5 minutes; current research has shown that results with less samples / shorter sampling time do correlate with the initially proposed 5 minutes. The new recommendation is one minute, which however may differ when using PRV, the optical sensor (technical constraint; that would be the case with all applications using this data); you can use your chest strap too however to measure HRV). I was very happy to donate for a beer, thank you!

Great app, thanks for sharing with us.

Great APP, but I would like to ask to the developer a way to export the tcx or gpx file to .xls file. I would like to put all my data in a file to run some analysis I have tried many ways, but nothing works. Thanks for your help

Hi, Thanks for the review. You can use FitToCSV.bat to convert the FIT file produced to a CSV file. You then need to find the right fields/columns to get the data you want. You can message me if you want further help. Note on older devices you can create a debug file in the LOGs folder - instructions on my webpage.

I downloaded this because I wanted more data than the Garmin HRV Stress app. This definitely hits the mark on that, and it works very well on my Fenix 5. I need to learn more about it, but the developer has clearly done the homework and made a really thorough app. Grateful to have it and looking forward to using it more.

Great app and easy to use. Fantastic communication from David on a technical issue. Highly recommended

Hi, Rather than giving a bad review you could have reached out. Seems there may have been a glitch with Garmin. Lots of other 4S users have no issues.... regards, David

Hi there! Nice app! Just to clarify - what is the final result stands for? (in my case) W=128,9 is this value in ms? Thx

Utviklerens svar
1. mai 2022, DJM_007

Hi, Glad you like the app. The website describes this display (link in the description ). Basically M = monthly and W = last week's average HRV. The number in the circle is the current measurement. Email if you need anything else. Regards, David

Very impressed. Using this on a Venu 2 and it's on par with an HR strap / app combo. Love the customizability and ease of use.

Will the app also upload data to Garmin Connect? If so, how should I find this?

Yes. Enable FIT writes either in the apps menu or under app settings in connect. You will see a white circle turn red as recording starts. Regards, David

Jow should it be measured? Standing or lying down ?

31. mars 2022, DJM_007

Hi Hendrik, I usually do the test sitting still and comfortably. Any position at rest without stress or raised heart rate or blood pressure will give the best result. Also try at the same time each day. Regards, David

All seems fine so far. Just curious, may have been answered already but will the app automatically switch to my HRM reading when I am wearing it? And use the watch sensor when not?

Utviklerens svar
29. mars 2022, DJM_007

Hi, Thanks for the review. The app now uses the sensor hub built in. Essentially if a strap is detected (it is listed in your sensors/accessories) it will connect to this in preference to the OHR. Regards, David

Hi Andrew, Rather than leaving a poor rating you'll get a better response by emailing me to debug your issue. Please a) read the instructions and b) check that the FIT Write option is enabled. this and release 1.1.2 seems to work on most devices

Hi, I downloaded android tranfer app on my Macbook connect to watches and went to garmin/app/logs folder where is only one file CIQ_LOG.BAK. I changed to CIQ_LOG.txt and it is not working. Can you help me?

Hi, the website shows you how you need to name the LOG file. Note that on the Fenix 7 series this doesn't seem to work but I am investigating. Any issues just email me. Regards, David

Benutze die App nun sein Anfangs Jahr jeden Morgen nach dem aufstehen. Nutze das Messergebniss um mein Körpergefühl abzugleichen und so mein Training zu steuern. Komischerweise wird die Aktivität nun seit 2 Wochen in Garmin Connect als Krafttraining aufgezählt. Keine Ahnung wie ich das vorstellt oder wieder ändern kann.

Hallo. Ich habe den Aktivitätstyp in der letzten Version geändert, da er hinzugefügt wurde, um Aktivitäten auszuführen, was Probleme für den Trainingsplan der Leute verursachte. Ich könnte sehen, ob ich dies konfigurierbar machen kann.

The HRV trend screen only shows me a number for w. I’m assuming that’s for women vs men. I’m a male and can’t find where/how to change that. Thanks.

Hi, The website in the description explains the display. M means Month and W means Week. The App picks up your sex from the watch settings and displays an age/sex related range of expected values in the arc. Hope that helps.

hi. Thanks for the review. Just enable FITWrite in the menus and Garmin will pick up the activity result and display the data.
