I had a fitbit for 4.5 years until it just died. It was useful, but once google bought them I’m glad it did. I have a Huawei watch, it’s so advanced it feels futuristic, so many great features. I only wish the interface was a little bit more customizable, but the amount of info it gives me about my health is great, helps keep me motivated and is like less than half the cost of an Apple watch. Highly recommended.

There is a ton of information that smart watches can tell you, I don’t think you fully understand the scope. I have a Huawei one.
