Jan Koum, the co-founder and CEO of the popular messaging service, on Monday announced that the mobile-messaging app now has 430 million active users. WhatsApp had close to 200 million users in April 2013, which means its user base has more than doubled in less than a year.

Koum also revealed that the service has more users on Android than on any other platform.

Taking a dig at picture messaging service Snapchat and Tencent's WeChat, he said that the company would not focus on things like disappearing photos and games.

He also reiterated that WhatsApp will continue to remain ad-free.

"We just want to focus on messaging. If people want to play games there are plenty of other sites and also a lot of great companies building services around advertising," Koum said at the conference.

He mentioned that monetizing the service was not an important thing at the moment and that the company wants to make sure ‘WhatsApp has a service that works’.

Koum also assured that the service does not collect users’ personal information in any form.

WhatsApp had last announced that it had achieved 400 million active users milestone.
