Kik Messenger was released on October 19, 2010 by Kik Interactive. On November 5, 2010 just 15 days after its launch, Kik Messenger got up to 1,000,000 user registrations.

Kik, is a chat application for smartphones that is quicker and more social than SMS.

How it works
Once downloaded, the app will scan your address book, and tell you which of your friends have downloaded Kik.
You can then start chatting with them immediately. Like IM, it’s asynchronous, it lets you see messages immediately, including when the person you’re chatting with is typing. Additionally, it lets you know when they’ve actually read their message. You can send friends an invitation containing the install link via text, tweet or email and Kik will also suggest users to you.

Kik has also released a new version of Kik Messenger today for iOS and Android devices that features real-time group chat for up to ten people. And Kik Messenger’s new picture sharing features allows users to share what they’re seeing on the fly.

Mobile messaging startup Kik Interactive has raised $8 million in Series A funding from RRE Ventures, Spark Capital, and Union Square Ventures.

Available at the appstore and the Android market
