General fitness tracking is serviceable and often close enough for casual use, but auto-detected sessions can need editing and this is not framed as a serious sports watch.
Across general fitness use, reviewers described the tracking as accurate and among the best all-round smartwatch performers.
There is no built-in GPS, but connected GPS through the phone was repeatedly described as accurate enough for distance and pace comparisons against Garmin devices.
GPS performance was widely praised for clean, precise tracks, though one race comparison still slightly favored Garmin.
Broader health readings come across as useful and directionally solid, but at least one reviewer found Oura more precise for sleep timing and staging.
