Speaking at the ATD Dive into Mobile conference, Snapchat CEO Evan Spiegel revealed over 150 million photos are shared through the social app every day. That represents a near-threefold increase from December, when the company announced over 50 million Snapchats — which delete themselves after ten seconds — were being sent each day.

It's perhaps a testament to the its unique take on sharing that it's difficult to draw direct comparisons with other apps and services. When compared to Apple's iMessage, which handles around a billion messages every day, Snapchat is undoubtably small — and cross-platform applications like WhatsApp often process more than ten billion daily messages. More permanent photo-sharing services such as Instagram, by contrast, handle far fewer; Instagram users share around 40 million photos per day.
