A new study by Similar Web has shown that WhatsApp is now the top messaging app in 109 countries.Equating to over half of all countries around the world, the Facebook owned messaging service is now installed on 95% of all android devices and is used for around 37 minutes per day on average.In second place, being the most popular messaging app in 49 countries, was Facebook's own Messenger app which was the most used in markets such as the US and Canada.Viber was the only other messaging service that came top in over 10 countries, including Iraq and Sri Lanka, whilst Line and Wechat's success was limited to a few countries like China and Japan.Some apps dominated the market domestically, like Kakao in South Korea or BBM in Indonesia, but scored very low elsewhere.
