Speaking of swimming, if you fancy taking any of these fitness bands for a dip, both are waterproof and support swimming tracking for up to 5ATM.

Both Fitbit wearables support smartphone notifications, tout sleep tracking tools, step counting, 24/7 heart rate tracking, and a host of dedicated workout modes such as running, cycling, and even pool swimming. As for GPS, both the Inspire 2 and Inspire 3 piggyback off your smartphone’s GPS, meaning workouts - such as outdoor runs, for instance - can be tracked more accurately.Īside from sensors, everything else is pretty much the same deal.

Neither device sports an ECG, which can be used to check your heart's rhythm and electrical activity, mainly because the costly sensor would bump up the RRP too much.

It can rapidly detect even small changes in oxygen levels, which - if they fell too low - could indicate serious health defects. This basically allows you to measure your blood's oxygen saturation, which is an overall indicator of wellness. So what can we expect from each of these Fitbit wearables in terms of feature set? Both fitness trackers have an optical heart rate monitor for heart rate measurement, but the Inspire 3 adds infrared sensors for blood oxygen monitoring.
