Heart rate variability (HRV) based daily readiness and custom HRV recordings.
Kubios HRV app uses scientifically validated heart rate variability (HRV) algorithms (used by scientists all over the world) to provide reliable information about your wellbeing and daily readiness. To make HRV measurements with the app, you need a Bluetooth heart rate (HR) sensor, such as Polar H10. Kubios HRV app has two modes of operation:
1) Readiness Measurement Mode monitors changes in your daily readiness status. By doing short (1-5 min), controlled resting HRV measurements regularly, you will receive reliable information about your physiological recovery and/or stress, how it changes from day to day, and how your HRV values compare with normal population values. Readiness monitoring is used by professional athletes in training optimization but can also be used by sports enthusiasts or anyone interested in their wellbeing, as it provides objective information about overall bodily stress as well as cardiovascular health.
2) Custom Measurement Mode, designed for researchers, health and wellbeing professionals, and sport scientists, conducts various types of HRV recordings. This measurement mode supports test-subject management, short- and longer-term measurements, live data acquisition, as well as event markers. Since the app is built with Polar mobile SDK, it can read live data from Polar sensors, including electrocardiogram (ECG) and heart beat interval (RR) data from Polar H10 sensors and live photoplethysmogram (PPG) and inter-pulse interval (PPI) data from optical Polar OH1 and Verity Sense sensors. Thus, when used together with these Polar sensors, the custom measurement mode provides an easy-to-use, light-weight, affordable way to obtain ECG, PPG and RR/PPI recordings. Regarding RR recording, the app also supports other Bluetooth HR sensors available on the market. Kubios HRV software license, which supports this measurement mode is required to store measurement data.
HRV is a reliable measure of autonomic nervous system (ANS). It tracks the beat-to-beat changes in RR interval arising from the continuous regulation of heart rate by the sympathetic and parasympathetic branches of the ANS. Kubios HRV analysis algorithms have achieved gold-standard status in scientific research, and our software products are used at roughly 1200 universities in 128 countries. The main HRV parameters include the parasympathetic nervous system (PNS) and sympathetic nervous system (SNS) indexes, the computations of which have been optimized, using a large reservoir of scientific research results, to provide accurate interpretation of recovery and stress.
I use the iPhone accelerometer-based readiness measurement every morning. I’d love Apple Health integration and Shortcuts/App Intents support. Ideally I could trigger a readiness measurement from a Shortcut and automatically write the resulting HRV value to Apple Health without taking screenshots. But other than it does the job well and for free
Doesn’t pair with HR sensor
Dan T. 123
I have a polar H9 heart rate monitor, which should absolutely be supportable given that they support the H 10 and the only difference is that the H9 does not support off-line (unpaired) use. Since this app is receiving the data live, that’s not an issue, and there is no difference between the two monitors otherwise. so my guess is that there is a bug, when you go to the settings, page to try to pair the monitor, it just shows a blank screen. It says my sensors and other sensors and no entries whatsoever. I’ve tried all the different approaches that they recommended on their website and it does not work. If this is fixed, I’d be happy to update my review.
Works great. More cautious than elite HRV

I appreciate the algorithm that this app uses, especially when my sole use is to prevent injury fatigue. The only request I have from a programming standpoint is to move the top menu bar down to centimeters so it can be used on iPhones 11 and above.5/5 functionally.
Best HRV app
jrobertblack
Best hrv app hands down, no bloated app trying to do too many things, clear straight forward results telling you the activity from your parasympathetic and sympathetic nerves.
