Their abilities scale as you go up in price-the Inspire 2 only keeps tabs on heart rate variability, plus breathing rate and skin temperature during sleep. While trackers aren’t replacements for proper health monitoring, Fitbit’s latest models come equipped with various sensors that watch for potential changes to wellness and stress levels. In other words, only the Charge 5 lets you ditch your phone when you go on a run or bike ride. The key difference on that last point: For the Inspire 2 and Luxe, you’ll need to lean on your smartphone’s GPS to gather the data. You can also track 20 different exercise modes including swimming, biking, and running, as well as see your real-time distance and pace.

You get up to 10 days on that entry-level model, while the color screen on the Luxe chops its battery life to half that, up to five days. The Inspire 2’s monochrome display may not dazzle, but it can go the distance on battery life. The Luxe sports a slightly larger 0.76-inch color display, while the Charge 5 has the most real estate with a 1.04 inch screen. The monochrome Inspire 2 comes with the smallest screen, measuring 0.7 inches. The Luxe and Charge 5 include six-month trials.
