I don’t understand this author’s idea that the galaxy watch should have a fitbit interface, and the idea doesn’t make any sense.

I have used fitbit, garmin, and android wear/WearOS trackers including samsung watches before and after the move to WearOS.

I do care about activity tracking, and the extent to which samsung health/my galaxy watch 5 pro accomplishes tracking is more than adequate. I used a Garmin Venu 2 Plus and its sleep tracking was worse than the galaxy watch (which is saying something). Fitness and GPS tracking, I’ve found as samsung health has improved since the galaxy watch 4, are as close as make no difference. With the garmin you get better battery life but at the expense of not having as many smart features. Same is true for fitbit watches. But I really can’t point to a specific thing I think fitbit does better other than sleep tracking. Fitness tracking are as similar as makes no difference, and subjectively I don’t particularly like fitbit’s general UI experience.
