Your fitness tracker data is pretty much useless for doctors

Wearable gadgets are a great way to gather information on your fitness and health habits, but what do you do with that information once you’ve gathered it? Giving it to your doctor probably won’t help you, because there’s nothing of value that they can do with that information, and many of them wouldn’t trust it even if there was. There’s nothing indicating that wearables can gather information on your health as well as certified medical equipment can, and there’s a lot of data indicating that they can’t, which means the information they gather probably isn’t even reliable.
