Instagram and Facebook are seeing some big numbers these days, as the number of users seems to be steadily increasing year on year. But while Facebook is probably where the haters go to delete old photos, the newest reveal from WhatsApp is that more than 2 billion people used it to communicate in 2018.

WhatsApp is the latest messaging service to announce its engagement levels. In its pre-IPO filing (now available on F-1 website), the company revealed the total daily active users (DAUs) jumped from 1.5 billion to 2 billion, on a y/y basis. The same figure represented 590 million paid subscribers.

WhatsApp’s humongous growth rate was seriously impressive in 2018: it added more than 1 billion new users last year. For comparison, Facebook and Instagram generated 565 million and 250 million new users respectively.

Now that you’ve read our earlier article on why you should be keeping tabs on WhatsApp’s rate of user growth, let’s get to the juicy details:

The company got a lot of attention for its tracking system that shares WhatsApp data with advertisers. Facebook had been testing the same in its Messenger service. WhatsApp has acquired a study done by a company called Discourse that claims ads on the social network’s platform increased people’s Facebook activity rates by 30 percent.

WhatsApp is also well on its way to improve its end-to-end encryption by adding a new feature on December 2018: word of mouth feedback. The company will start delivering a feature that will let users “collect feedback” from users even if they are not using the latest version of the app.

WhatsApp’s latest growth was much more impressive than the one announced by a mobile messaging service in Asia: ZTE’s WeChat app, which has around 1.8 billion users across all the markets, including China, has recorded a drop in the total DAUs in 2018.

Our friends over at ANUGA noted that ZTE’s MAUs have seen a sizable fall year on year. The results were released via the Financial Times, and comes after an anonymous survey of 450,000 WeChat users in China conducted by Yotpo Consulting. The drop was noticed as early as 2016, according to the analysis.

In comparison, Instagram’s monthly active users (MAUs) jumped from 868 million in 2016 to 1.4 billion as of last month. The app continues to grow, and the recent acquisition of Dubsmash, which claims more than 50 million MAUs, may be the key behind it.
