WhatsApp has Over 800 Million Users,600 Million are on Android A few months ago the company WhatsApp revealed that it has at least 800 million users. However, there is a new study that reveals some astonishing figures.Out of the over 800 million people that use this instant messaging app for messaging and voice calling services, more than three quarters are reported to be using Android devices. This means that at least 600 million people use WhatsApp on Android.The study was conducted by GlobalWebIndex (GWI), and it involved about 50,000 active internet users, with WhatsApp segment constituting around 12, 606 users from 34 countries across the globe. According to the findings, 73% of those using WhatsApp use it from Android devices while those using the iPhone followed from a distance with 22% of the market share. This means that the remaining 5% is shared among users of Windows Phone, Nokia, and BlackBerry devices.WhatsApp has almost 1 billion usersIn January, WhatsApp revealed that it has reached 700 million users. A few months later on in April, the company revealed that it was sailing on a user base of more than 800 million people. Based on this growth matrix, it is true to say that WhatsApp currently has more than 900 million monthly active users, a figure that could easily rise to 1 billion by the close of the year 2015.WhatsApp made a record by becoming only the second non-Google app to achieve the 1 billion downloads™ mark on the Google Play Store.  However, as you may have noted from the above stats, this figure does not equal the number of active users of the app. Nevertheless, when this number of downloads™ figure is placed on the official number of active users of WhatsApp, it is obvious that Android takes home the lion share, hence the unsurprising nature of the GWI report.WhatsApp growth is a reflection of global smartphone updateWhatsApp keeps adding more and more users to its user base, and this can be attributed to the continued number of smartphones in the world markets. The general number of Android smartphones in the handset market is more than any other company; hence, the huge number of WhatsApp users on this platform.Android is an open source operating system and for sure, it seems the door to new entrants to the platform won™t be closing anytime soon. According to a recent study, there are over 24, 000 unique Android manufacturers/devices, an increment of 28% from last year total. Most of these devices are very cheap, going at $200 or less and are available in most emerging markets.A research by the IDC revealed that Android is used on more than 78% of devices around the world while iOS only manages 18.3%. We see the same figures with WhatsApp for Android and WhatsApp for iOS respectively.
