On the Sense 2, notifications are first proceeded by a splash screen announcing the app (and when applicable, either the name of the sender or the number of notifications). You can also input health details like menstrual cycles and blood sugar readings in the Fitbit app, which is accessible through your smartphone or the web interface. But fitness trackers have never been precision instruments having an expanded array of activities for manual tracking helps balance the scales. Even when you are doing something that matches an auto-tracked activity, like walking, it’s not always as accurate as starting a manual tracking session.

Fitbit’s auto-tracking is limited to just six categories-walking, running, biking, swimming, elliptical, sports, and aerobic workouts-and its trackers (including the Sense 2) will try to apply these categories to whatever activity you’re actually doing.įor example, my dance sessions were splintered into irregular fragments labeled as “Sport,” “Aerobic Workout,” and “Swim,” mere minutes apart.

This broader array of options is a major improvement. Additionally, the Sense 2 can manually track an expanded set of other activities, with over 20 options like CrossFit, kickboxing, dance, and cross-country skiing. Several basic exercises (including running and biking) are also recorded automatically. My resting heart rate estimates ran 2 to 3 bpm higher on average, which concerned me at first until I figured out it was the tracker, not me. And the accuracy is decent enough to keep most number nerds happy, though you may find some variation compared to the Charge 5 and previous Sense. It captures a boatload of data automatically-you get stats on steps, heart rate, and sleep, plus info that can clue you into the potential onset of illness or general health issues (skin temperature trends and blood oxygen saturation), possible heart-related health issues (ECG readings), and rising stress levels (continuous skin conductance). As a souped-up fitness and wellness tracker, there’s much to like. The Sense 2’s large screen makes it easy to see all your stats at a glance.įitbit’s sequel to the Sense should be an easy recommendation.
