Apple has continued its focus on its health focus with the Series 4. In addition to being able to detect a fall, this new Apple Watch introduces three heart-rate tracking features that will be available later this year. It lets you know if your heart rate is too low, it can detect irregular rhythms (which may indicate atrial fibrillation), and most impressively, it serves as an FDA-cleared electrocardiogram.
Most stores that sell these smart watches feature display models that you can pick up and touch. We recommend getting a feel for how these watches operate before you invest in one of your own. Specifically, you’ll want to know the form of navigation each of these use to go through the various screens, apps, and functionalities. We were partial to twistable bezels and dials, but you might be used to swiping your way through screens.
What’s on display?: Most smartwatches have full-colour displays, though the underlying technology will determine how good the screen looks. There has been a move towards AMOLED (active matrix organic light emitting diode) displays, as used in the Apple Watch which present a bright screen, crisp text and accurate colours. Fitness trackers tend to have lower-quality screens and may not present in full-colour, partly to save battery life.
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.
