Apple Watch may not be accurate as you think,

The first thing that always crosses my mind when testing fitness is the accuracy of the data. Smart watches and Fitness followers Not cheap, and if you use it to monitor something crucial like your health, the accuracy is important.

Everyone and their brother wears somewhat TraceWhether that Apple Watchand Google Pixel watchand Aura episode or whoop. It is estimated that one in three Americans is used A device that can be worn For health and fitness tracking features. This brings me back to whether these things can be trusted. If it is not accurate … What is the point? Should we all return to analog?

Researchers from Mississippi University Filter analysis of 56 studies Compare this from Apple Watch with reference tools when measuring factors such as heart rate, number of steps and burning energy. Although there are always some expected errors, we have a more specific answer to the amount of shares you should put in the numbers you see in your watch.

Apple watches are good in measuring steps and heart rate

The results of the twist analysis show that Apple Watch accurately measures the heart rate and the number of step. We know this based on the average error measurement in the absolute percentage (the standard method of measuring accuracy) reported for each sanitary scale.

The heart rate was a percentage of 4.43 %, while the number of steps was 8.17 %. Anything less than 10 % is excellent, so you should feel confident in what your Apple Watch says about the heart rate and the step for today.

However, it should not depend on the energy spending scale

The same cannot be said about power expenses or burning calories. The percentage was wrong for this scale 27.96 %. This is a great leap in inaccuracy. The researchers found that the power expenses are inaccurate in all the activities tested, including walking, running, mixed exercises intensity and cycling.

This is not a new problem. Many studies have found that smart and tracked watches do not do a great job Calculating calories burning. It can be 40 % out to 80 %. A different study revealed that the Apple Watch 9 series can vary in energy spending and heart rate measures Skin.

Although this study was for Apple watches, I expect similar trends across other devices because it often measures the same. One study found that Vitteb was an average error of 27 % when Measuring burning calories.

Smart watches account How many calories you burn? Throughout the day, using factors such as your movements, heart rate and data from sensors within the watch. Other factors, such as your age, weight and gender, are included in this account. None of them will be 100 % accurate.

Where does this and your data leave you?

This news does not scare me as a smart watch, using my daily data to track training and sleep. I still think the smart watches of the data give us a great way to stay enthusiastic.

I used the Google Pixel 3 watch Watch my heart health Thanks to the heart loading scale. When it comes to sleep, I noticed some accuracy when it comes to sleeping and waking up, although it is not a big difference. Most followers use the heart rate and your movement Follow your sleepSo it is not surprising to see a degree of error. There are always some errors, and for use, this is good. Use my data for progressive directions, instead of very granular data. Although if you are a serious athlete that tracks calories, it is necessary not to rely on your smart watch for this number.

Your smart watch is a tool to guide you during your well -being. Use it to build habits and make meaningful changes, not to diagnose medical conditions. However, I will not count Smart watches features Like Apple’s vital application, fall or detection Disclosure of a pulse loss The feature that Google Pixel gets.

Apple and other brands are constantly released updates to improve their technology over time. And if you are wondering Any smart watch you should get For the best accuracy, it is difficult to say. They all have their tracking methods, even if they interfere often. There is no perfect, so it is better to choose the person who suits your budget and the best.
