If your Samsung Watch runs Wear OS, it can record your HRV data automatically. We called this feature Health Monitoring. Just wear your watch throughout the day and check Welltory for your measurement results — they should appear in your feed several times a day.

To enable automatic measurements, you only need to upgrade Welltory to the 4.3.0 version or later on both your phone and watch. After updating the app, you can see the Galaxy Watch section in Menu. If you can see the green checkmark near the Health Monitoring text, your watch is successfully connected, and the Health Monitoring feature is on.

You can adjust the monitoring frequency in the Samsung Watch section of Menu. This option sets the minimum time between two consecutive automatic measurements that can be taken with your watch, not the exact times at which measurements are taken. Please note that your Samsung watch automatically measures your HRV only when you are calm and relaxed. It doesn’t take a measurement while you’re asleep, moving, or working out.

If you want to take a measurement with your Samsung Watch running WearOS right here, right now, open Welltory on your watch, make sure your watch fits snugly on top of your wrist, and try not to move. Keep silent, and don't aim to control your breath consciously. Press the red button on your watch — a measurement will start.

When you're done, open Welltory and check out your feed to see the results.

If you have a Pixel Watch 2 or 3, it can automatically measure your heart rate variability.

Just wear the watch at all times, and we'll do it all for you - under favorable conditions, when we can make an informative automatic measurement, we'll take it and send you the results in a feed. The watch only does automatic measurements in situations where you are relaxed and calm. The watch will not take HRV measurements while you are sleeping, exercising, or moving in any way.

To start using the automatic measurements feature, you need to update Welltory on your phone and watch to version 4.19.50 or higher. Once the app is updated, you will see in Menu → Settings → Primary device under Smartwatches the option to connect Pixel Watch 2 or 3.

You cannot set the frequency of automatic measurements yourself. If you want to take a measurement with your Pixel Watch 2 and 3 right now, open the Welltory app on your watch and press the red button.

To ensure a high-quality measurement, make sure the watch fits snugly in your hand, do not change your body position, do not move the arm on which you are wearing the watch, do not control your breathing, and do not talk. When the measurement is complete, open the Welltory app and wait for the results to appear in the feed.

Make sure that the watch is charged and connected via Galaxy Wearable or Google Pixel Watch and the airplane mode is off on your watch and phone.

The watch may have been disconnected from the phone, or you may have interrupted the measurement with a sudden movement. If that’s not the case, make sure you've allowed Welltory to access Activity and Body sensors in Settings → Apps → Welltory → Permissions. After giving the necessary permissions, try to manually launch the Welltory companion app on your watch and take another measurement.

If we can't find your Samsung Watch or Pixel Watch connected when you start a measurement, we propose you use your camera to take a measurement.

Alternatively, you can manually switch to camera measurements via Menu → Settings → Primary device. Once your watch is charged, be sure to reselect it in Settings.

In the Premium version, users can take an unlimited number of measurements per day.

However, in the free version, you are limited to only one manual measurement with your Samsung or Pixel Watch and one automatic measurement per day. When you reach your daily limit, you'll see the following message on your watch:

Currently, the 300-beat mode is not supported for watch measurements; it only works for camera measurements. However, we plan to reintroduce this feature for watch measurements in one of our future releases.
