How They Work: Technology Behind the Trackers
Both devices rely on optical sensors for heart rate monitoring, but Fitbit’s TruePulse 2.0 claims improved accuracy during high-intensity workouts (Fitbit, 2023).

Sleep tracking algorithms differ: Garmin adds Pulse Ox for blood oxygen monitoring, which can detect breathing disturbances (NIH, 2022).
Neither device has built-in GPS; both depend on connected GPS from your smartphone, which can influence accuracy depending on phone settings and signal strength.
