Elevate your day with the Fitbit Sense Advanced Health and Fitness Smartwatch with wrist-based heart rate sensor. It offers multiple features such as tools for heart health, stress management, skin temperature trends, SpO2 and more, all in a premium design. With Sense, assess your heart rate for AFib with the on-wrist ECG app, detect and manage stress with the EDA sensor--and thanks to the integrated on-wrist skin temperature sensor, the Sense watch records your skin temperature every night to show how it varies from your personal baseline. You can also see your nightly blood oxygen levels (Sp02) at a glance. Always-On display mode allows you to see real-time exercise statistics and check the time with just a glance, even when your hands are full. Turn it off to be more discreet. Use Google Assistant or Amazon Alexa built-in voice assistant to ask your smartwatch questions, set alarms and check the weather (availability and features may vary). The lithium polymer battery has a 6+ day battery life (varies with use and other factors); plus, fast charging gives you a full day’s charge in just 12 minutes. The case is water resistant to 50 metres For convenience, load your credit and debit cards to your Wallet in the Fitbit app, then use your Sense smartwatch to tap and pay for your purchases quickly, easily and securely. Plus, Sense unlocks a 6-month trial of Fitbit Premium (for new Premium users only). Must activate with device purchase. Valid payment method required.
