Fitbit Versa 2 Smartwatch Health and Fitness with Heart Rate 
1. Use Amazon Alexa via your voice to get instant news and information, check the weather, set timers and alarms, control your smart home devices and much more (third party apps may be required; amazon Alexa not available in all countries).
2. Based on your heart rate, sleep time and restlessness, sleep scores help you better understand the quality of your sleep each night. Also track your time in light, deep and REM sleep stages and get personal insights.
3. Control your Spotify app, download Pandora Station and add Deezer playlist (subscription required; Pandora US only).
4. With a larger display and always on-the-go option, your data is always at a glance (the display always needs to be charged more frequently).

6. Works 24 hours a day with 6 plus daily battery life (varies with usage and other factors).
7. Receive notifications of calls, texts, calendars and smartphone apps if your phone is nearby. Also send quick reply and a voice reply only on Android.

After swimming or soaking the band, we recommend drying the band because, like any wearable device, it is best for your skin if the band is clean and dry.
