How do you know if your wellness device data is actually useful?

The way I look at it, the question isn’t really how much data a device gives you, it’s whether you’d actually do anything different based on it. That’s the only test that matters for me.

I had a stretch where I was checking my sleep numbers every single morning, and after a couple months I realized I was basically reading the same story over and over. Bad night, tired. Good night, fine. The number never told me anything my body hadn’t already told me before I even got out of bed. So all that extra detail was just sitting there looking impressive.

The stuff that actually changed my behavior was the boring stuff. Step count, because it nudges me to take a walk I otherwise wouldn’t. That’s it. Everything else was entertainment.

So when you’re eyeing an upgrade, I’d ask whether there’s a specific thing you’d do differently with the new numbers. If you can’t name it, it’s probably noise.

I’d stay put for now. I upgraded once for more stats and ended up ignoring most of them after a couple weeks. The only number I still check is my resting heart rate, and my old tracker already showed that just fine.

I’d stick with what you have for a bit longer and pay attention to which numbers you actually look at without thinking. If you’re only checking one or two things, a fancier device probably won’t change much. I upgraded once and the extra stuff was fun for a week, then I just went back to the basics.

Probably not worth upgrading for sleep scores alone.

Upgrading just gives you more stuff to scroll past. The one thing that actually changed my behavior was the heart rate graph during workouts, because I could see when I was slacking. Everything else was noise. Save your money.

I went through a phase where I was convinced more data would magically make me healthier. Bought a fancier tracker with all the recovery scores and training readiness stuff. Used it religiously for maybe two months, then realized I was just staring at numbers and still doing the exact same workouts I did with my old cheap one.

The thing that actually changed my behavior was way dumber than any of those scores. My old tracker had a basic weekly step total. Seeing that number get close to a round figure made me take a walk on days I otherwise wouldn’t have. That’s it. Not recovery scores, not sleep stages, not any of the fancy stuff. Just a plain number I could beat.

What I noticed with the upgrade was that I spent more time interpreting the data than acting on it. Like I’d check my “readiness” in the morning and then basically do whatever I was already planning to do anyway. The extra info gave me something to think about but nothing to actually do differently.

So my honest take is that the useful data is usually the boring stuff you already understand. If a new metric requires you to google what it means or read a guide to interpret it, that’s a sign it’s not going to change your routine. The stuff that sticks is the stuff you intuitively know what to do with. For me that’s steps and maybe weight trend. Everything else was just entertainment I paid for.

I mostly look at whether a number makes me do something different that day. If it doesn’t, it’s noise to me.

For example, I had a stretch where I was checking my resting heart rate every single morning for like two months. Not because I had a plan, just because it was there. Then I noticed it was creeping up on days after I’d had a couple drinks or stayed up late. That actually made me cut back on weeknight beers for a while, which I probably wouldn’t have done otherwise. So that one number earned its keep.

The sleep stuff never did that for me though. I’d see a bad score and just feel annoyed about it, not change anything. Same with step streaks. I’d hit some arbitrary goal and feel nothing.

My preference now is that I’d rather have fewer numbers that I actually understand than a dashboard full of stuff I can’t act on. If I can’t explain to myself what I’d do differently based on a reading, it’s just entertainment. Not saying that’s wrong, sometimes it’s fun to look at. But I wouldn’t pay extra for it.

So I guess the test is whether you’ve already changed something because of the data you have. If not, more data probably won’t fix that.
