An all-new sensor and Google AI combine for Fitbit’s most spot-on heart rate tracking yet. New sensors for heart rate tracking, skin temperature, and stress management. Fall detection helps connect you to emergency services if you’ve had a hard fall, even auto-dialing if you’re unresponsive. If you’re feeling unsafe, your Pixel Watch 2 can easily alert trusted contacts or 911 with Emergency SOS. When out for a run or walking alone, set the timer. If it expires with no response, your watch can share your location with close contacts. Go even longer with 24 hours on a single charge and always-on display.
