It also says 300 million people use the app every day, compared with 100 million daily active users for Snapchat.

Instagram is halfway to 1 billion users. 

The photo-sharing app announced Tuesday morning that it has passed 500 million monthly users. That's up from 400 million in September, and the company notes that those 100 million new users were added faster than the previous 100 million. 

While monthly users is the standard metric for measuring the growth of social media companies, Instagram is also touting that it has 300 million people using the app every day, compared with 100 million daily active users for Snapchat. 

Instagram's user base is still a fraction of the size of parent company Facebook, which has 1.65 billion monthly active users. Facebook-owned WhatsApp, meanwhile, has 1 billion MAUs. But Instagram remains larger than Twitter, with 320 monthly users. 

A large part of the app's user base, 80 percent, comes from outside the United States, which represents 100 million monthly users. 

The company, led by CEO Kevin Systrom, has also said that, on average, 95 million photos and videos are shared every day, and that those posts average 4.2 billion likes per day. 

The announcement comes a little more than a month after Instagram unveiled a redesign and logo change. As part of the app's update, it has begun rolling out a new, non-chronological feed prioritizing photos based on an algorithm.
