      For fitness its probably decent but Garmin seems to have placebo sleep tracking. In order to get anything remotely accurate the sleep tracking algorithm has to be compared to a lot of polysomnograph data. But because companies don’t want to spend any more than they need to sleep tracking is usually just tacked on. Garmin hasn’t shown a good track record in this regard.
