WhatsApp, the popular instant messaging app owned by Facebook, is now delivering roughly 100 billion messages a day, the company’s chief executive Mark Zuckerberg said at the quarterly earnings call Thursday.

For some perspective, users exchanged 100 billion messages on WhatsApp last New Year’s Eve. That is the day when WhatsApp tops its engagement figures, and as many of you may remember, also the time when the service customarily suffered glitches in the past years. (No outage on last New Year’s Eve!)

At this point, WhatsApp is just competing with itself. Facebook Messenger and WhatsApp together were used to exchange 60 billion messages a day as of early 2016. Apple chief executive Tim Cook said in May that iMessage and FaceTime were seeing record usage, but did not share specific figures. The last time Apple did share the figure, it was far behind WhatsApp’s then usage (podcast). WeChat, which has also amassed over 1 billion users, is behind in daily volume of messages, too.

In early 2014, WhatsApp was being used to exchange about 50 billion texts a day, its then chief executive Jan Koum revealed at an event.

At the time, WhatsApp had fewer than 500 million users. WhatsApp now has more than 2 billion users and at least in India, its largest market by users, its popularity surpasses those of every other smartphone app including the big blue app.

“This year we’ve all relied on messaging more than ever to keep up with our loved ones and get business done,” tweeted Will Cathcart, head of WhatsApp.

Sadly, that’s all the update the company shared on WhatsApp today. Mystery continues for when WhatsApp expects to resume its payments service in Brazil, and when it plans to launch its payments in India, where it began testing the service in 2018. (It has already shared big plans around financial services in India, though.)

“We are proud that WhatsApp is able to deliver roughly 100B messages every day and we’re excited about the road ahead,” said Cathcart.
