The Apple Watch Series 6 and Fitbit Sense are top smartwatches that can help keep an eye on your fitness levels and act as a phone alternative on your wrist. Both also have an electrocardiogram (ECG or EKG — Apple uses ECG) app, track workouts, sleepand blood oxygen levels, but they’re different in the way they go about doing these things. To help you decide which is right for you, I’ve compared them on everything from fitness tracking to battery life and overall performance.
If you have an Android phone, the Fitbit is your only option, but both work with iOSdevices, making the decision trickier if you have an iPhone. After two weeks of wearing these watches, I can tell you that there is no one-size-fits-all option. If you want the best overall smartwatch, with seamless fitness tracking and safety features, get the $399 (£379, AU$599) Apple Watch. If you want the most robust sleep tracking, temperature sensor and the best battery life, get the $329 (£299, AU$499) Fitbit Sense.
Apple Watch Series 6
The best all-round smartwatch

Lexy Savvides/CNETThe latest Apple Watch has a robust set of fitness tracking features, an FDA-cleared ECG, blood oxygen tracking and all the responsiveness you could want from a smartwatch. It’s also the better option if you need built-in LTE to use your watch without your iPhone nearby.
