Google has introduced the $179 Fitbit Edge, a new fitness tracker with a 1.34-inch OLED display, built-in GPS, ECG support, week-long battery life, and Fitbit's first user-replaceable battery. "And unlike the Pixel Watch, it's compatible with Android and iPhones via the Google Health app," reports Wired. From the report: The Edge has a user-replaceable battery, a Fitbit first, aligning with Google's efforts to make its Pixel Watch more repairable. (Likely also due to new battery regulations set to take effect next year in the European Union.) Repair options will vary by region and availability. If you find the Pixel Watch's round face too bulky, the Edge's capsule-shaped alternative might suit smaller wrists better. If the Charge 6's 1.04-inch display was too small, the Edge upgrades it to a larger 1.34-inch screen. The difference is noticeable, and that extra real estate could make a real impact when glancing at your metrics mid-workout. The Edge borrows a few more attributes from the Pixel Watch, including an altimeter that uses atmospheric pressure to measure elevation changes. That means it can record elevation gain and loss during outdoor activities, track floors climbed, and add more context to your outdoor stats. It also has a far-field skin temperature sensor, replacing the standard device temperature sensor found in other Fitbits. By bringing some of the Pixel Watch's more advanced hardware to a fitness-first wearable, Google is giving the Edge a compelling middle-ground position in its lineup at a Fitbit-friendly price. The Edge inherits the Fitbit Air's improvements while restoring several Charge 6 features the screenless tracker lacks, including built-in GPS and electrical sensors that work with the electrocardiogram (ECG) app. You can also control music playback on a connected Bluetooth device, as you could with the Charge 6, and Google Maps turn-by-turn directions will arrive later this year. [...] With a Google Health Premium subscription, the Edge can track blood pressure trends without manual calibration and insulin resistance trends without requiring a blood draw. Google first announced these capabilities alongside the Pixel Watch 5's debut, but they only became available at the end of September. They're also available on the Air, keeping Google's screenless tracker up to date as its lineup expands.Read more of this story at Slashdot.
