About 105 million people used the Opera Mobile Store from Opera Software in December, a statistic big enough to rank it as the fifth largest app store, the Norwegian browser maker said Tuesday.
The company's app store offers 200,000 mobile apps for a variety of device types with a variety of operating systems -- Android, Symbian, BlackBerry, iOS, and Java.
The top type is a Java app, but in 2013, Android apps nearly matched it, accounting for with 42.7 percent of downloads, Opera said.
New users grew by a factor of 1.7 compared to 2012, Opera said.
Opera's app store has its roots in the company's 2011 acquisition of Handster. The top app stores, however, remain Google Play and the Apple App Store.
