Now there multiple varieties of Fitbit available to suit many different groups of customers. It’s hard to believe that the first product Fitbit released back in 2009 was a clip-on device that only measured steps and sleep. The Apple Watch 7 has a slightly larger screen, but otherwise wasn't a huge upgrade from its predecessor (Image credit: Apple) There's a 70% brighter always-on screen mode for use indoors, the display is topped with tougher crystal, and the watch's case is now rated IPX6 for protection against dust. It retains the 7's slightly larger case sizes (41mm and 45mm compared to 40mm and 44mm for the Apple Watch 6). The Apple Watch 8 is a relatively iterative upgrade, with the main difference being the addiction of new functions like Crash Detection to detect car and bike accidents, and skin temperature sensors. Fitness is the primary function of the Apple Watch in 2022, so if that's your main concern then you won’t go far wrong here. The Apple Watch 6 and above include many of the same features, including blood oxygen monitoring, plus an on-demand ECG. The SE, especially the latest version, is a great entry point for those who want an Apple Watch with a heart rate feature at the lowest price. All are fundamentally excellent smartwatches that benefit from a mature operating system, so it's a matter of balancing your budget against their features. It’s best to see the Apple Watch versions as good, better, and best. All of the above use Apple's latest operating system for wearables, watchOS 9, which introduced new mindfulness tools, improved outdoor cycling features (including more accurate calorie counting for e-bikes), a pilates workout mode, and an updated photos app with new portrait watch faces.
