The average time a local mobile user spent on the video streaming app in January stood at 30 hours and 34 minutes, or 59 minutes a day, according to mobile app tracker WiseApp, based on data of Android and iOS users over the age of 10 in the country.

Users aged between 10 to 19, however, spent the most time on the video streaming platform on average last month at 46 hours and 52 minutes per user, followed by the 20s age group at 41 hours and 31 minutes and the 30s age group at 27 hours and 10 minutes. (Yonhap)
