sorry. Smart watches are not as accurate as you think.

Sensors in today’s smartwatches can detect your heartbeat, track how you sleep, and even monitor blood oxygen levels. If Apple gets their way, you could track your blood sugar on your watch (and even send a report about it to your doctor).

Have you ever wondered, “How accurate are these smartwatch readings?” We took a look because you are not alone. Smartwatches and fitness watches have some serious flaws that you should be aware of.

Paging Doctor Watch

It turns out that cramming multiple sensors into a small watch doesn’t produce the most legitimate results. Who knew? Don’t panic if you experience a spike or drop in sleep or blood oxygen levels. Everyone.

  • The sensor has a skin color issue. The situation has gotten so bad that users have filed a lawsuit against Apple, claiming that the blood oxygen sensor does not work properly on dark skin. Ahh! However, studies have shown that this can be a problem for many blood oxygen sensors.
  • Watches do not reach medical-level accuracy. Advanced research is limited, but this study conducted on Garmin fitness watches found that the watches were unable to measure energy expenditure or blood oxygen levels with sufficient accuracy to make medical decisions.
  • Pedometers and calorie trackers are easily fooled. Smartwatches like the Apple Watch 6 and Fitbit Sense stink at measuring calories burned and can have a hard time defining step counts. And don’t get me started on how vague sleep tracking is!

Okay, smartwatches only help guests with a lot of guesswork. But what can we do to make them better?

Take care of your health

Here are some figurative steps I think every smartwatch user should take while getting to the literal ones (free word play included!).

  • Adjust the watch size to fit your wrist. A loose watch that slips off your arm causes many accuracy issues. Buy something you can adjust.
  • Focus more on your heart rate than steps or calories. The pulse is right there, so it’s no surprise that the watch is more accurate about heart rate than anything else.
  • Don’t let reading stress you out. Ironically, such stress increases heart rate and other essentials. Even worrying about tracking your sleep can cause insufficient sleep (doctors call this orthosomnia). Rather than thinking of your readings as hard numbers, think of them as a general brushstroke of your health.
  • Watch readings over time instead of individual numbers. These charts and graphs are more helpful than going by the numbers.
  • If you are concerned, visit your doctor: Don’t waste time or energy obsessing over what the clock tells you. If you have serious concerns, make an appointment like an adult.

My smartwatch chooses

If you don’t already have a smartwatch, here are some great watches:

🤣 It’s great to have a smartwatch. On the one hand, there are those that can be used to respond to text or content. to On the other hand, It’s not like that. (Was that the moaning I heard?)
