I LOVE my Apple Watch, best money I ever spent.

IMO depends on your personality. My mother and sister both have Apple watches. My mother, a thin perfectionist, uses it to guide her fitness and benefits greatly. My sister, an overworked and extremely overweight perfectionist, uses her watch as a watch but ignores it for fitness; she has had every incarnation of fitness wearables but she lacks self discipline and has emotional eating issues. I think the wearables actually just remind her of how poorly she’s done to meet her goals.
