When you log into your Facebook account through Facebook Messenger, you’re presented with a list of your online friends. You can proceed to chat with a friend via text, or if the friend is also running the Facebook Messenger app on their phone, you can connect for a free VoiP chat. If your friend is using Facebook on their computer, Facebook Messenger will send them a link that takes them to a Website where they can speak with you via a Flash-based VoiP app.

Facebook Messenger also lets you post pictures, browse message history, view a friend’s wall, use emoticons, receive instant replies via Push Notifications, and set up sound notifications and multi-tasking support from within the app. According to a company representative, Crisp App will eventually introduce paid plans for calling regular phone numbers as well.

Facebook Messenger costs $3 and requires iOS 3.1.2 or later.
