Fitbit has been expanding the range of its tracking sensors since well before its acquisition by Google. Just last month, the company added support for monitoring blood oxygen saturation and skin temperature to the Charge 4, but now it's looking to expand beyond surface-level information. In an effort to combat high blood pressure, Fitbit is launching a study to determine if its devices can track changes in your heart, right from your wrist.
Fitbit makes some of the most useful fitness-focused wearables these days. The company unveiled its new Sense smartwatch in August with the world's first electrodermal activity (EDA) sensor for detecting stress levels, and compatibility with a new ECG app that could even help users avoid strokes by alerting them to irregular heart rhythms. At least, it would, but at the time Fitbit was still waiting on FDA approval for that functionality. Now the feature is becoming available as the new ECG app rolls out to users.
During my brief stints using Samsung Galaxy smartphones, I eschewed many of the company's branded apps, but Samsung Health was one of the few exceptions. I was impressed by how robust and slick it was and found myself tracking my blood pressure and SpO2 level every now and then just for fun. Now the Korean tech giant is bringing that health app know-how to Samsung HeartWise, a new health app built for a niche audience: patients who want to keep up with their doctor-recommended heart wellness program via their smartphone and Gear S3 smartwatch.
My arsenal of smart health and activity trackers has been missing a body composition weight scale. The Fitbit Aria always looked appealing to me because I've been wearing a Fitbit for more than 3 years, but it's getting a little outdated. Several months ago, I was looking at the Polar Balance Scale, the Withings WS-50, the Garmin Index Smart Scale, and a few others. Eventually, I settled on the QardioBase because I already had a good experience with the QardioArm and liked the company's no-nonsense approach to design and health. However, I was unlucky enough to get the first generation, which turned out to be a complete failure from the get-go.
