Instagram is growing faster than ever.

On Wednesday, the Facebook-owned app revealed that it has 700 million monthly users, up from 600 million in December 2016. The last four months marks the fastest Instagram has ever added 100 million additional users, a spokesperson told Business Insider.

Wednesday’s announcement comes on the heels of Instagram revealing that its ephemeral Stories feature has more daily users than Snapchat.

Unlike Snapchat, Instagram’s user base is primarily international, as 80% of its users are outside of the US. Brazil, for example, is the app’s second largest market with 45 million users.
