Both offer a rated 10-day battery life, but with the color touchscreen and ambient light sensor, you can likely expect the Inspire 3 to require charging more often. There are a few other things to note with these two trackers. For anyone who suffers from breathing issues or a condition like sleep apnea, and wants to keep a close eye on their breathing stats, this additional feature alone could be worth the upgrade. The one feature in this department that the Inspire 3 has that the Inspire 2 does not is Sp02 monitoring, which advises of your breathing rate and oxygen saturation. Other features included with both are cardio fitness score, stress management score (Premium only), Daily Readiness Score (Premium) that advises when your body is ready for a workout or when you should take a rest, skin temperature variation, reminders to move, and menstrual health tracking. You can also set a goal for the number of daily active minutes you want to get and work towards meeting that each day. Sleep Profile, however, is only available with a Premium membership, as is access to a Sleep Score.īoth support Active Zone Minutes, which will advise when you enter fat burn, cardio, or peak heart rate zones, a great way to get the most out of a workout and, conversely, to ensure you don’t overexert yourself. The detailed sleep tracking not only includes stages of light, deep, and REM sleep, but also the new Sleep Profile that compares your sleep patterns over time with that of an animal. There are also mindfulness breathing sessions to help stay calm and relax.

This includes common workouts like walking, running, and swimming, in case you forget to manually track a workout.īoth also track 24/7 heart rate, and provide notifications if an irregular heart rate is detected without a specific reason (like you’re in the middle of a workout).

They both work with the Fitbit app and can track the basics, including daily steps, calories burned, and various exercises with AutoTrack. The primary reason for getting a fitness tracker is to, well, track fitness.
