Yes, I totally agree with you. Bar code scanner would be brilliant, it saves time and it just so much easier. I know a lot of other competitor brands have a bar code scanner and calories counted and burned information. I'm actually quite shocked that Samsung health doesn't have this on its app, considering as I'd rate Samsung as one of the best brands for technology. I've been looking at buying a galaxy watch 3 to help with my fitness & weight loss but without the calorie counter and burned information I really don't see the point, especially when there are a lot of other brands that do have them with their watches for a lot cheaper in price. Even if it's not 100% accurate, it really helps to keep ppl on track with their goals.
