It offers a lot more functionality than the Luxe, with a similarly attractive design for only $30 more. Fitbit has removed Spotify support from this generation, but added several useful health monitoring features that were previously only available on its $299.95 Sense smartwatch, including an electrodermal activity (EDA) sensor that measures small electrical changes in your skin's sweat level to track your body's response to stress, and an electrocardiogram (ECG) app that checks for signs of atrial fibrillation (AFIb), an irregular heart rhythm that can lead to blood clots, stroke, heart failure, and other serious complications. Now in its fifth-generation, Fitbit's most popular device finally has an AMOLED color touch screen and a metal case, making the $179.95 Charge 5 a wearable you actually want to wear. Last year's Fitbit Charge 4 was an excellent fitness tracker held back by a dated grayscale display and a cheap plastic build.
