The Luxe is also Fitbit's best-looking fitness tracker to date, with a stainless steel case and buckle and a choice of either a soft silicone band or a gold-toned stainless steel bracelet. That means less scrolling, which is always a win in our books. Your daily data is presented on a super-sharp color AMOLED display, which offers lots of detail in a very small space. When we put it to the test, we were particularly impressed by its heart rate monitoring accuracy, which was on par with much more expensive running watches. The Luxe tracks everyday activity, sleep, heart rate, respiration and workouts.

The Fitbit Luxe is our number one fitness tracker thanks to its excellent health monitoring tools, stylish design, and the strength of the fantastic Fitbit app that works alongside it. Some are even less obtrusive, such as the Oura smart ring designed to passively monitor sleep. How they look on your wrist is important, and most come in a slim design, but others pack a bigger clock face and more buttons. Of course, the other important aspect when choosing the best fitness tracker for you is style. Check our fitness tracker vs smartwatch guide to find out the difference.

Of course, depending on your budget some fitness trackers may be more advanced than the cheaper versions, so you may find yourself picking which features are the most important to you. Most of the best smartwatches and all of the best running watches contain fitness tracking hardware, but are often more expensive than the simpler band-style trackers. Once your data is measured they can start to give you a better picture of your overall health and fitness, allowing you to tweak your habits to more positive ones. All fitness trackers are different, but there are some basic requirements to look for, including long battery life, on-wrist comfort, built-in GPS, and the ability to track your fitness and monitor your heart rate. These bands track metrics such as sleep, steps, calories expended, and log your workouts.
