I have used Kubios almost daily for over 5 years. I have used it to track various lifestyle changes with diet, exercise, sleep, breathing exercises, and meditation. My HRV has improved considerably-at 60 years old, mine HRV was age appropriate (not so good). At 68, it is dramatically improved to the level of a 20-year-old (similar measurements with Elite HRV. I measure my HRV daily. I have tried the beta test that uses a cell phone accelerometer, and I got the same readings as with me polar H₉.

Kubios is free. It gives you the raw numbers and not some invented, proprietary bs that you can never ever interpret on your own. Kubios gives you straightforward numbers that you can work with. It is a tad slow to load both the phone app and the desktop app. Unfortunately, I can’t download individual measurements from the phone app as a data file to work with using the Kubios HRV desktop app. The baseline should be user-definable. I’d prefer a baseline of the last 60 days, whereas others might prefer longer or shorter baselines. Every now and then, the phone app exits out of the blue, usually when it should be saving the readings, and you have to do a new reading. The desktop app also gives you heart rate zones based on your maximal heart rate, possibly also considering your resting heart rate. They could be a bit more transparent and actually inform users how exactly they get to those zones. I had to calculate the zones myself, which came out as follows: Zone 0 (Inactive) = < 45%; Zone 1 (Very Easy) = 46-60%; Zone 2 (Easy) = 61-70%; Zone 3 (Moderate) = 71-80%, Zone 4 (Hard) = 81-85%; Zone 5 (Maximal) = 86+%. The phone app gives you your daily readiness in four categories: Very Low, Low, Normal, and High. I have come up with my own training rule, which is as follows: If my readiness is very low, I do a Zone 1 workout. If it’s low, I do a Zone 2 workout. If it’s normal, I do a Zone 3 workout, and if it’s high, I drop the fu….. Hammer. The app is great. It wouldn’t really make sense for Kubios to make it a paid app because you can always download the free Kubios desktop app and analyze your readiness there; you would just need a watch that saves R-R intervals, which most of the modern sports watches do. I believe that the Kubios HRV app will remain free for the foreseeable future as the Kubios desktop app has always been free and can do the very same thing and a heap load of more stuff than the app.

Does6 not connect to the Polar H10 which is working fine when tried with other apps (Polar Beat, Elite HRV etc.)
★☆☆☆☆Constant Van Wyk· Mar 16, 2023
Terrible. Can't connect to an HRM that uses Bluetooth or ant plus. I mean these are universal protocols. WTH?
★★☆☆☆Rune Magnussen· Aug 6, 2023
Gives the same HRV score every day. The HR and other values varies but the score remains the same. You don't need the app I can tell you your score, it's 63%. Every day. Forever. Other apps may have inconsistency problems but at least they give you different results on different days. The two stars are for all the info you get to ponder about, like PNS and SNS and all the rest that probably means something to a doctor but not me. I used the Polar h10.

Forces me to register to get my data. Does not connect to my Polar H10.

Latest update doesn't work for the polar h7 sensor. It will show connected but start button will remain greyed out.

Totally confusing. Doesn't give heart rate variability reading but gives all other readings. Says it needs 6 heart rate readings which are 3 minutes long, didn't save one of them thus wasting 18 minutes of my life for no read out. App goes.!
