The TicWatch GTH Pro smartwatch analyzes your arterial health

While smartwatches have typically opted to measure heart health through electrocardiograms, Mobvoi has announced that with the TicWatch GTH Pro it’s taking a different approach. The company says its latest fitness tracker can measure a person’s long-term blood health.

Mobvoi partners with Cardie X

The TicWatch GTH Pro was developed over two years in partnership with Cardie X; specializing in health technologies. According to Mobvoi, the TicWatch GTH Pro has a new “Arty Heart Health” analytical platform. It non-invasively measures central arterial waveforms.

It basically measures the strength of your pulse to provide information about your heart health. Although the watch does not measure your blood pressure. The platform is based on technology that measures central and brachial blood pressure data. Experts believe that blood pressure taken from the central artery may be a more accurate measurement than traditional blood pressure taken from the arm; and that it might be a better predictor of heart disease.

The TicWatch GTH Pro gives you your Arty score

The TicWatch GTH Pro is equipped with two optical heart rate sensors; one measuring the frequency at the wrist and the other on the side of the watch. As with EKG smartwatches, you’re supposed to place a finger on the side sensor to take daily readings.

This makes sense, as the wrist isn’t the most accurate area for heart rate reading; due to the sound of moving tendons, muscles and bones. The fingertip is a better area to measure heart biometrics; but it also has its drawbacks.

From these daily readings, users get an “Arty Score” which represents their overall heart health based on four metrics. These are exercise capacity, estimated arterial age, cardiac stress, and heart rate. Exercise capacity refers to blood flow to the heart. While arterial age is based on the “stiffness” of your arteries. As for cardiac stress, it is based on pulse pressure.

A wide range of advice

As the tracker is meant to track long-term progress, Mobvoi says it will provide personalized recommendations based on user settings. For example, if the device detects that your exercise capacity is reduced, it will recommend that you “return to healthy habits”. Like getting 150 minutes of moderate exercise a week or adding vitamin C to your diet.

These are important assertions that should be taken with a grain of salt; especially since Mobvoi claims that the device itself has not received Food and Drug Administration clearance in the USA.

Technically, FDA clearance isn’t really needed here. Indeed, the watch does not claim to have diagnostic capabilities. EKG watches, for example, require FDA clearance because they can detect early signs of atrial fibrillation.

Instead, Mobvoi cites Whoop – a recovery tracker aimed at athletes – as a similar product that also provides general health information from biometric heart data. That said, the technology underlying the GTH Pro’s ability to measure blood pressure, ATCOR’s SphygmoCor, has received FDA clearance. Moreover, it has been used in clinical trials and research.

Other features of the TicWatch GTH Pro

Besides tracking heart health, the GTH Pro also measures SpO2, body temperature, and respiratory rate. The smartwatch can also track 14 different activities, set alarms and send notifications. Battery life is rated at 10 days and water resistance at 5 ATM. She is also able to track sleep and stress using heart rate variation.

At $99, this smartwatch is also much more affordable than most trackers and smartwatches with advanced heart health features.

The Mobvoi TicWatch GTH Pro is available today on Mobvoi and Amazon.
