Apple Watch andWearOSusers already knowall about Cardiogram’s health and fitnesscharts and trackers, but now there’s a newwearable brandgetting in on the act. Beginning today, any Fitbit device with an optical heart-ratesensor canlink with the Cardiogram app on their iPhone or Android phone.
While there aren’t any newFitbitfeaturesin the Cardiogram app, Cardiogram’s business development chiefHarishKilarusaid Fitbit devicesbringunique benefits to theprogram:“Since Cardiogram takes heart rate readings in the background, Fitbit’s extended battery life has been an obvious plus,” he said. “Duringinternal testing, we’ve also seen remarkably clear resolution of [heart rate] data, which helps users consistently track how events throughout the day affect their heart rate. And then Fitbit’s native sleep tracking provides automatic tagging of HR data during sleep, within their Cardiogram timeline.”
One thing Cardiogram won’t be able to access, however, is Fitbit’srelative SpO2 sensor, which estimates the amount of oxygen in theblood in order to test for sleep apnea and other ailments.That’s because Fitbithasn’tturned it on yet,but once it does,Cardiogram could use it toaugmentDeepHeart,an AI modelthat monitorsheart rate variabilitytotrackthe warning signs ofcomplex diseases including sleepapnea and diabetes. The sensor would add a layer of data that isn’t offered on any other smartwatch, and it could help Cardiogramdevelopa smarter, more accuratemodel.
Fitbit users can download the Cardiogram app for free in the App Store or Play Store, or they can upgrade to Cardiogram Premium to share their data with family and their physician.
