Instagram today announced hitting 100 million monthly active users, less than a month after reaching 90 million. The milestone follows a controversy that erupted in December after the New York Post reported the photo-sharing app had lost about a quarter of its daily active users in the wake of its terms-of-service debacle.

Instagram-owner Facebook called the data “inaccurate,” maintaining it continued to see steady growth both in registered and active users of Instagram. Facebook subsequently cut off public access to the daily user data used in the Post story.

Instagram is the third highest-ranked Android app and the No. 17 free iOS app in the U.S., according to AppData, which tracks apps integrated with Facebook. In November, Instagram extended user profiles the desktop Web, and earlier this month added its image feed to the Web so users can browse photos outside the app.
