The EDA Scan app is capable of detecting electrodermal activity, which can provide insights into your body's response to stress. Additionally, a built-in skin temperature sensor tracks your skin temperature each night, allowing you to monitor any variations. The device comes in two band sizes: Small, fitting wrists of 140mm-180mm in circumference, and Large, fitting wrists of 180mm-220mm in circumference.
By using the Fitbit ECG app (only available in select countries), you can assess your heart for atrial fibrillation, a heart rhythm irregularity, and easily share the results with your doctor. Note that this app is not intended for use by individuals under 22 years old. The operating temperature of the device ranges from 14° to 113°F.
With an on-wrist skin temperature sensor, you can track your skin temperature each night and observe any fluctuations. The device also allows you to view your nightly blood oxygen levels with a quick glance at the various clock faces available. The radio transceiver is Bluetooth 5.0 compatible, and the operating temperature ranges from -10° to 45° C.
Stay informed about your heart health with high and low heart rate notifications that alert you if your heart rate seems unusually high or low compared to your average. The battery life lasts over 6 days, and fast charging can provide a full day's charge in just 12 minutes (battery life varies based on usage and other factors; up to 12 hours with continuous GPS usage). Use the built-in GPS feature during your runs, hikes, bike rides, and more to track your pace and distance without needing your phone nearby. Additionally, the built-in mic and speaker allow you to take Bluetooth calls hands-free when your phone is within close proximity, though this feature may require more frequent charging.
