Wickr is one of many young chat apps, like FireChat, focusing on secure messaging. The company says it keeps your chats completely anonymous (it doesn't track any metadata), it heavily encrypts everything, and it also lets you maintain ownership of everything you share. It also lets you set specific expiration times for your messages, which gives you more control than something like Snapchat.

"Our main mission is to create the private web," founder and CEO Nico Sell told us. "I think Facebook has done a good job of creating the public web, but that's only one half of it." But she added Wickr also plans to move more into the public realm eventually, it just won't be the company's main focus.
