Although the body is smaller the screen is larger and provides more information, including displaying text messages and other notifications from your phone. Swipe down to see your notifications, up to see your stats, and left to relax or exercise. It isn't as intuitive as it perhaps could be but you get used to it. You can choose a watchface from a range of built-in options in the app, including some which display your heart rate at all times. The heart rate appeared fairly accurate when compared to my Apple Watch Series 4 and old Fitbit Alta.

The new built-in 'relax' feature is a great idea in theory, though I didn’t find having my breathing judged by a watch particularly relaxing in practice. When you do a good, deep breath you’re supposed to get sparkles, and despite doing some truly excellent deep breaths (in my opinion, anyway) I only got the sparkles 20 per cent of the time, which was annoying. No one wants to lose at relaxation, and the gamification of breathing is weird.

One big improvement over previous versions of the Charge is that it’s now fully waterproof and can track swimming. This is great news for swimmers and sweaters alike. It can, with reasonable success, track running, cycling, swimming, treadmill and weights exercises, plus it acts as an interval timer, and you can choose from nine more exercises in the app (but you can only have six at a time on the device). It is important to note, though, that it doesn’t have built-in GPS, so you’ll need to bring your phone with you when you run if you want location data. It also doesn’t do music in any way, so you’ll probably have your phone with you regardless.

What’s odd, though, is that the two major features of the Charge 3 —Sleep Score and blood oxygen level from the SpO2 sensor — aren’t available in the app yet. They sound like great features, which makes their lack of usability on launch curious.

All in all it’s a solid medium fitness tracker. Unless you’re a swimmer it’s probably not worth upgrading from the Charge 2, despite big improvements, but it is certainly worth it from the original Charge, or from an Alta HR.

The Charge 3 is what you get when you want to track your fitness in more detail, but don’t want the extra expense or distraction of a smartwatch, and in that regard it’s exactly what it should be.
