⌚️ Apple Watch misleads users about calories burned

📰 The frequency of errors in calorie counting averages 28%, and sometimes reaches even 80%.

💔 The gadget also unreliably tracks sleep, especially falling asleep and waking up, as trackers rely on heart rate and movement rather than brain activity.

🏃‍♂️ The researchers had no issues with heart rate and step tracking. For fitness watches, the margin of error is insignificant (4% and 8%).
