If you want the app, notification, and style advantages of an Apple Watch but need better fitness tracking, you can upgrade to the Apple Watch Series 3 and get built-in GPS, as well as waterproofing that allows swim tracking. But the Series 3 costs more than a fitness tracker or even many running watches, and it still has compromises compared with a dedicated fitness tracker, such as a lack of dedicated physical buttons. We think serious athletes are better served by a fitness-specific device.
But the Ionic, the first of Fitbit's devices to include an SpO2 monitor, came out more than one year ago. It's frustrating to hear about exciting features that are "coming soon," when "soon" ultimately means not weeks or months, but years. While I understand it takes time and effort to develop features like this (especially if Fitbit hopes to pursue medical device clearance or approval from the FDA in the future), I don't think Fitbit should hype features that it isn't ready to let users put to the test.
The watch faces themselves are classic Kate Spade designs. You get a sultry winking moon face with perfectly curled lashes, calling you a leading lady; cute bubbly balloons for a digital watch face with numbers; a speeding cab that reassures you that you'll be there in a New York minute; and a daisy that loses petals as the time ticks away in a classic game of "He loves me; he loves me not."
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
