After all, that's almost double the number of active users of Twitter, which went public with about 230 million active users this fall.
Now, though, WhatsApp co-founder and CEO Jan Koum dropped the fact that the app has already shot to 430 million active users in only a month, TechCrunch reports.
Snapchat, by comparison, had about 30 million monthly active users in December.
Koum, speaking at the DLD Conference in Germany, also said users send and receive a whopping 50 billion messages through WhatsApp daily.
He made another bold statement, too: Koum promised that WhatsApp will continue to stay away from "gimmicks" like disappearing photos and games. WhatsApp won't try to be a Snapchat killer anytime soon.
WhatsApp makes money by charging users $.99 per year to use the app after the first year.
