Rant: My fitness tracker review was a mess because of bad accuracy
So I picked up this new fitness tracker last week, thinking it would be cool to test out. I wore it all day, even during my runs. But right away, I noticed the step count was way too high. Like, it said I walked 15,000 steps when I was mostly sitting at my desk. The heart rate monitor kept jumping around during exercise, so the data was no good. I followed all the setup tips online, but nothing fixed it. It's got me wondering how much we can trust these gadgets. What do you all think? Have you run into similar problems with trackers you've reviewed?

The idea that trackers aren't medical gear is true, but that doesn't mean the data is useless. Some models are actually pretty good for basic stats. My old Garmin watch was within 2% of a chest strap for heart rate during steady runs. The problem is the cheap sensors in a lot of budget wearables. They can't handle quick movements or different skin tones well, which is why the readings jump around.

Remember, these gadgets aren't medical gear, so maybe don't stress too much. @danielnelson is right to question the accuracy, in my view. But from what I've seen, they're still okay for rough trends.

Accuracy really matters if you're using data to make changes to your routine. When a tracker says you burned 500 calories but it was actually 300, that can mess up your diet plan. Heart rate zones are key for training, so jumps in reading mean you might be working too hard or not enough. How can you trust a gadget that can't get the basics right? It's not just about trends, it's about having reliable info to act on.
