New Delhi: 

It was found that the Apple Watch, known for being easy to use and having more health functions, made fewer errors in measuring heart rate and steps. Researchers noted that the calorie count displayed by the models was often inaccurate for all users and brands. The research found that users find these numbers to be informative, yet they may not be completely reliable.

A report released recently indicates that the Apple Watch gives an accurate reading of your heart and steps, but its calorie count can be significantly off. A study at the University of Mississippi looked at 56 studies and discovered the average error in calories was almost 28% which is much higher than the range allowed for fitness devices.

Calorie estimates miss the mark

The biggest issue came with calorie tracking. Researchers found that the average error was close to 28%. It is more than three times the acceptable limit for an accurate measurement device. The difference was noticed in every type of exercise, including walking and running.

Room for improvement in new models

Researchers found that newer models are getting better over time. While every update might not be very significant, it seems that Apple is gradually making calorie counting more precise. This information may guide their future work on sensors and algorithms.

Heart rate and step counts are reliable

The results indicated that heart rate and step counting had few errors. The difference between the heart rate measured by the watch and the real reading was only 4%, but the step counts were wrong by 8% on average. Since this is an average performance for fitness wearables, the Apple Watch is still able to track your daily activities.

Apple’s response and ongoing role

Apple has made it clear that their calorie counts are not meant for medical use. Apple claims the Apple Watch is intended for general health purposes, not for medical use. Apple has introduced sleep apnoea detection, but it has not shared the method it uses for calorie tracking.

Researchers suggest that this analysis should not stop people from wearing wearables. The aim is to inform users about what these tools can and cannot do. When developers understand what helps and what doesn’t, they can create devices that are more useful for health and fitness.
