Instagram has been around for what feels like forever, but it seems like just yesterday that the app migrated over to Android after being a long-time iOS exclusive. Today marks one year of Instagram’s presence on Android, and to celebrate the company shared on its blog that in just that short time almost half of its users come from Android. Last we heard, Instagram had over 100 million active monthly users in February, growing at a rapid pace at that. The push over to Android was a huge part of that, garnering over 1 million downloads in the first 24 hours. At the time, Instagram had around 30 million installs on iOS. Since then, Instagram has been acquired by Facebook for $1 billion. Both iOS and Android have maintained steady growth since that fateful April afternoon. In fact, just two weeks after the acquisition Instagram announced that it had surpassed 50 million active users, with 5 million new sign ups per week.
