According to their findings, “Of the 187 countries that SimilarWeb examined, WhatsApp was the world leader claiming 109 countries, or 55.6% of the world. WhatsApp’s countries include Brazil, Mexico, India, Russia, and many other countries in South America, Europe, Africa, Asia, and Oceania.”
Given that WhatsApp last reported that they had 1 billion users, we guess this shouldn’t really come as a surprise. That being said, coming in at second place is Facebook Messenger in which it claimed 49 countries which includes Australia, Canada, and the US. Considering that Facebook made it mandatory to download the app to chat on the mobile version of Facebook, this shouldn’t really be that much of a surprise either.
Now like we said, there are some apps that prove to be more popular in some countries than others, and BBM is a perfect example. According to Similar Web, BBM was installed on 87.5% of all Android devices in Indonesia, while countries like Australia, the US, and the UK don’t even even the 5% mark.
