With the built-in Alexa voice assistant, you can quickly get news and information, check the weather, set timers and alarms, control smart home devices, and more – all with just your voice (third-party apps may be required; Alexa is not available in all countries/regions). Based on your heart rate, sleep time, and restlessness, the sleep score feature helps you better understand your sleep quality each night. You can also track the time you spend in light, deep, and REM sleep stages and get personalized sleep insights. Get a 90-day free trial of Fitbit Premium to help you stay active, improve your sleep, and manage stress. Unlock additional features in the Fitbit app. (Requires a valid payment method. Cancel before the end of the free trial to avoid subscription fees. This offer is only available to new Premium users). A larger screen and always-on display make it easy to see information quickly (always-on display increases battery consumption and requires more frequent charging). You can play your favorite songs and playlists using the Spotify app controls on your wrist. You can also make secure payments with Fitbit Pay and receive notifications from your phone, text messages, and smartphone apps.
