Messaging app WhatsApp’s steady growth continues, according to a Facebook post by CEO Jan Koum. “Today, we’re thrilled to share that WhatsApp has more than 700 million monthly active users. Additionally, every day our users now send over 30 billion messages,” he wrote. That’s up from 200m in April 2013, 300m in August 2013, 400m in December 2013, 500m in June 2014 and 600m in August 2014. WhatsApp is thus currently adding around 25m active users a month, now of course under Facebook’s wing after the social network paid $19bn for the company. Unlike other messaging apps, WhatsApp has shown no appetite so far for expanding into media (including music), focusing instead on introducing encryption technology and (soon) voice calls. “As humbled and excited as we are by these numbers and our continued growth, we’re even more excited to keep building a great product in 2015,” wrote Koum.
