Fitbit Sense 2

The Sense 2 uses a continuous electrodermal activity (cEDA) sensor to monitor your body's physical response to stress throughout the day. When it detects potential stress, it prompts you to log your mood or perform a guided breathing or mindfulness session to help you manage it in the moment.

Yes, the watch is water-resistant up to 50 meters, making it safe for swimming laps in a pool or wearing in the shower. It tracks your swim workouts automatically, though you should rinse it with fresh water after swimming in salt or chlorinated water.

No, you don't. The Fitbit Sense 2 features built-in GPS, which allows you to track your pace, distance, and route accurately during outdoor runs, rides, or hikes without needing your smartphone nearby.

You can expect the battery to last over six days on a single charge, though this will vary based on your usage, such as how often you use the GPS or the always-on display settings.

Yes, the Sense 2 supports on-wrist Bluetooth calling. As long as your phone is within Bluetooth range, you can answer and conduct calls directly through the watch's built-in microphone and speaker.

The Sense 2 includes an ECG app that can assess your heart rhythm for signs of atrial fibrillation (AFib) and provide irregular rhythm notifications. While these tools are clinically validated, they are not a substitute for professional medical diagnosis or treatment.
