Kubios HRV Scientific 4.0 (the next generation of Kubios HRV Premium) have been released on 30.9.2022 and updates as well as maintenance extensions for Kubios HRV Premium have been thereby discontinued. Kubios HRV Premium users whose license maintenance is up to date can use the new software version for a limited time (depending on the length of the maintenance period). We have contacted all those Kubios HRV Premium license owners in October 2022 by email, providing details how to start using the new software version. If you have any questions, you can contact us at sa...@kubios.com.

New features available in Kubios HRV Scientific include support for Kubios HRV mobile app measurements, training data analysis, and ECG waveform analysis. The new version also supports small animal HRV analysis.

Kubios HRV Scientific license is a 1-year subscription license, which allows you to use Kubios HRV Scientific on one computer (one active session at a time). When you purchase the software, you will receive a license key. In order to use the software, you need to log in with a Kubios account and activate the software using the license key, which will link your Kubios user account with the license. The custom measurement mode of the Kubios HRV mobile app is also enabled for the licensed user (one active custom measurement session allowed at a time).

Kubios HRV Scientific license pricing is available at the product page. Academic pricing is available, but please note that under the academic license you may use the software only for non-commercial academic use and/or personal use (see End User License Agreement for details).

If your organization needs several Kubios HRV Scientific licenses, please note that we do offer quantity discounts. If you purchase 2-4 licenses, you will get 10 % off. If you purchase 5 or more licenses, you will get 20 % off.

Kubios HRV Scientific is a subscription license, with the subscription starting on the order creation date. The standard subscription period is one year, but we also offer the option for extended subscriptions of two or three years upon request (please inquire about a quote or custom order link from sa...@kubios.com).

When you purchase a license, you have the choice to store your payment information, enabling automatic annual renewal of your subscription. Rest assured that you will receive email notifications prior to any renewal charges, and you can cancel your subscription at any time to prevent further charges.

The custom measurement mode of the Kubios HRV app is designed for researchers and professionals for performing different kinds of HRV measurements. Kubios HRV app utilizes Polar SDK, and therefore, we recommend you use the app together with the following sensors:

For more information about measuring with Kubios HRV app, please see this video tutorial. The app is available in Google Play and AppStore, but for longer-term HRV measurements we recommend using Android devices.

By default, the Kubios HRV Scientific license enables you to use the software on one computer at a time (one active desktop session) and make one custom measurement with the Kubios HRV mobile app at a time (one active custom measurement session).

If you need to conduct multiple simultaneous recordings using the Kubios HRV mobile app, we recommend our Kubios HRV Scientific Group Measurement license. This license allows for multiple active sessions on the Kubios HRV mobile app. The Group Measurement license functions in the same way as a regular license, with the only difference being the number of active sessions permitted within the Kubios mobile application.

For clarity, please note that each active measurement requires one phone and one HR sensor. For instance, conducting 30 simultaneous measurements would necessitate 30 phones and 30 sensors. Additionally, ensure that you log in to the app with the same Kubios user account used for logging in to the Scientific software.

Kubios HRV Scientific Lite, formerly known as Kubios HRV Standard, is a free HRV analysis software for academic research or personal use. While the Lite version is perfect to start your HRV exploration, you should understand that it has limited functionality (compared to the full version) and you may use it only for non-commercial purposes. For details regarding how the Lite version differs from the Full version, see Lite vs. Full version.

Starting with certain models introduced in late 2020, Apple began the transition from Intel processors to Apple silicon in Mac computers. As a result, we offer two different macOS installers on our download page: one for Mac computers with Apple silicon and the other for Intel-based Mac computers. If you encounter issues running the Kubios HRV Scientific installer on your Mac, please ensure that you have downloaded the correct installer (note that the Apple silicon installer is not compatible with Intel-based Mac computers).

When you install Kubios HRV Scientific into a Mac computer using Apple silicon, you also need to install Amazon Corretto 8 (which is a Java runtime required to run the software). Kubios HRV Scientific installer will remind you about this requirement and provides a link to download the required Java runtime.

Kubios HRV Scientific (ver. 4.1) runs in Windows (64-bit Win 10 or 11) and macOS (Monterey, Ventura, or Sonoma). Kubios HRV Scientific was developed using MATLAB (The MathWorks, Inc.) and was compiled to a deployable standalone application with the Matlab Compiler. When you install Kubios HRV Scientific into your Windows or Mac computer, the correct version of MATLAB Runtime (MCR) that is required for running Kubios HRV software, is also installed. In general, the system requirements for running Kubios HRV software are thereby similar to those of Matlab (see ).

Kubios HRV app supports Bluetooth low energy (BLE) HR sensors, which measure and transmit beat-to-beat RR intervals to your phone. Since there are many HR sensors available in the market, we can not test them all and provide a complete list of compatible sensors. But you are welcome to check if your HR sensor can be connected to Kubios HRV app, even if it is not listed below.

In general, for accurate HRV analysis we recommend a chest strap HR sensor, which measures the electrical activity of the heart (i.e. electrocardiogram or ECG) and extracts RR interval values from it. Optical sensors, which are able to measure interbeat interval (IBI) data e.g. from the arm or finger, are convenient to use but their accuracy is not optimal. The beat detection inaccuracy in optical sensors is typically within 5 ms, which may produce as high as 10 % errors in HRV parameters.

Apple watch is not supported. Even though Apple advertises that the watch measures HRV, we cannot support the Apple watch because it does not transmit (in real time) RR intervals to third party applications.

The custom measurement mode in the Kubios HRV app runs in demo mode by default, which means that you can observe the data coming from your sensor but the data is not stored. In order to make custom measurements and store your measurement data in Kubios Cloud, you need a Kubios software license that supports this.
