Exactly. What is great is being able to look at trends over time. Having more sensors that generate more actionable data is good.
Congrats to you. My goals of losing weight and getting back into shape were the reasons I bought my first smart watch (the Basis Band from Basis Science, bought by Intel for $100 million and then killed). I am down almost 100 pounds over the last few years. Still about 15 pounds over my weight in high school when I played soccer almost every day. Still working on it.
See the trends was a big help to me as well. Not everyone has the same needs or motivators. I love the challenges I receive from my Apple Watch and I love being able to see that I hit my fitness goals every day.
If this data does not help you, do not bother to collect it, but stop complaining that others want it.
