An American study has found Twitter is the most accessed social media service on mobile devices.

Conducted by Crowd Science, the survey discovered 11% of Twitter users admit to accessing social media while driving, compared with just 5% of other mobile social media users. According to the survey, 27% of users tweet daily, 46% check their feed daily and 24% have never tweeted, or have ceased doing so.

The survey found 40% of Twitter users access the service on their mobile at least sometimes, juxtaposed with 32% for Facebook. Users accessing via mobile all the time reflect this disparity, with 8% for Twitter and 3% for Facebook.

Crowd Science also found that 17% of Twitter users had accessed social media from a restroom. 12% of non-Twitter social media users had done the same. Looking at motivation, the report found 17% of social media users do so because friends and contacts do, while 15% do so because stopping or reducing use would damage their social status.

Of Twitter users, 32% believe they spend too much time using social media, 22% have written things they later regretted and 16% say they often neglect important activities to spend time on social media.
