The Garmin Vivosmart 4 Smart Fitness and Activity Tracker uses fitness and wellness features such as activity, sleep, blood oxygen levels, and stress tracking to help you make the most of a healthier, more active lifestyle.

Benefits

• The Pulse Ox sensor estimates your body's blood oxygen saturation level to gauge how your body is absorbing oxygen
• Vivosmart 4 tracks your light, deep and REM stages of sleep, along with movement throughout the night
• Body Battery energy monitoring uses a combination of stress, heart rate variability (HRV), sleep, and activity data to gauge your body's energy reserves at any moment, so you can plan your day to optimize times for activity and rest
• By tracking your HRV (the time interval between each heartbeat), your Vivosmart 4 calculates and displays your stress levels to you know when you are having a calm, balanced, or stressful day
• Opt into the "Relax Reminder" which provides a vibration alert and a display message "Take a moment to breathe?" if your stress level gets elevated during the day
• In addition to steps, its fitness tracking capabilities include floors climbed, calories burned, intensity minutes and more
• Check the weather, control your music, receive smart notifications, find your phone, even reply with preset text responses (Android only), and access social media notifications on your tracker's display
