Our jaws dropped in December, when messaging app WhatsApp announced that it had 400 million monthly active users.
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.
