WhatsApp is a popular app that lets you set up group chats. The app lets you share pictures, videos, voice memos, audio notes, contacts, and location info. Even though WhatsApp has a lot of competition, it still remains as the dominant messaging app choice.
WhatsApp used to cost $0.99 on iOS, but they gone the “freemium” route now. WhatsApp users can download the app for free for a year, then they will be charged only $0.99 per year after that. Not a bad way to get a lot more users to join the service.
WhatsApp has already been doing this on Android, BlackBerry, Nokia, and Windows Phone. If you already bought the app for the $0.99, the good news is that you will not have to pay the annual fee of $0.99. WhatsApp currently has over 200 million monthly active users and is seeing around 10 billion messages sent / 17 billion messages received per day.
