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.

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.

Latest Kubios app release from Nov. 2023 doesn't run on my Android 10 phone now. It won't recognize my Polar H₉ HRM. Up until then it was working OK. I installed the app on my iPad, and it works OK there.

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

Bogus. Many people have ectopic beat, and this app is not able to handle them properly, randomly delivering very low or high RMSD. While they do not say what they really do, it seems like the app is incapable of recognizing and discarding ectopic beats and uses some primitive quality metrics instead. In that situation the app seems to face an impossible choice of either discarding all HRV and producing very low RMSD, or keep also HRV stemming from ectopic beats and produce very high RMSD

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.!
