Come on. There are thousands of smart watches on the market at this point. It's not like that Samsung one is super-important or has any unique features.
I find the fit3 very weird & a little disingenuous unfortunately and this is my opinion as it bears a striking resemblance to the Watchfit series from Huawei, both in Hardware & Software, and honestly the Watchfit series has two better features than the fit3, namely GPS & an animated personal trainer for 20+ workout routines,so I don't know what Samsung is trying, but I'd rather recommend the Watchfit series.
You can sideload the Huawei Heath app and it has been proven to be a better accurate step & sleep counter than most brands out there.
They are selling on Amazon and are on sale for $60 and are selling very well. I bought one in gold for my wife and she loves it. I tried it along side my galaxy watch 5 and I liked it so much more that I just purchased the silver. Not sure how many more they would sell in the USA with in store sales but most people do buy online these days.
The Galaxy Fit 3 won't be officially available in multiple key markets, and Samsung may be leaving money on the table, particularly in the US, with this poor decision.
