GENEVA, June 10 (Xinhua) -- One of every two adults in Switzerland, keeps track of their daily activities on their smartphones or other digital devices, a recent study published said.

A further 20 percent have tried these kinds of "lifelogging" systems at least once.

The study on how people measure their lives digitally was conducted by the Sotomo Research Center on behalf the Sanitas Health Insurance Foundation said this week.

The most popular logging activity was tracking one's daily step count, followed by mapping runs and walks as well as other sporting achievements.

These fitness tallies also led to behavioral changes for nearly half of all users, the study found.

The trend towards people digitally measuring their lives is "far from being exhausted", wrote the authors of the study.

The results were based on a survey of 3,055 people, representative of the permanent Swiss resident population aged 18 and over.

Health monitors focused on tracking sleep duration or heart rates are less commonly used. They also have a lower impact on behavior.

Two-thirds of people questioned said that they would like to make use of more extensive automatic monitoring systems, such as measuring their energy and resource consumption or the number of calories they eat.

At the same time, users had concerns about data privacy.

Over 70 percent said that they had deactivated certain smartphone functions, such as location tracking, for data privacy reasons, the study found.
