How many minutes a day do you spend on your smartphone? Of those minutes, how many are spent using a messaging app such as WhatsApp, Messenger, Skype, or Viber?
If you're like the average American Android user, you probably spend around 29 minutes using WhatsApp, 16 minutes on Skype, 9½ minutes on Messenger, and 8 minutes on Hangouts.

In the graph above, we looked at 10 of the top messaging apps in the world and compared their average daily Usage Time in the United States over Q1, 2016. When combining the data for all 10 of these apps, the average Usage Time is 23 minutes, 23 seconds, and KakaoTalk recorded the highest overall time in the US with close to 49 minutes a day.
Based in South Korea, the free messaging app is installed on less than 1% of US Android devices, but these users are extremely loyal to the app. On average, 37.8% of the app's users actually use the app on an average day.
Another Asian-based messaging app showing this kind of US app retention is Line, an app that has big plans to IPO in mid-June.
