Kik Messenger is the totally free, crazy-fast, cross-platform messenger app that connects you to your friends in real-time. You'll like its functionality but not the rather tedious account creation process.
Free but feature-rich: A cross-platform app, Kik Messenger offers all the chatting features you'd expect and allows you to share photos, sketches, and Web pages. Its smooth performance and small file size make it a good choice for older iPhones.
Message statuses: The app informs you whether a message has already been delivered (indicated by the letter D on top of a check mark) or read (R on top of a check mark). Messages can also be sent while the recipient is offline.
Built-in Web browser: The app's basic browser works well enough and even has Favorites, but don't expect to run Java or Flash elements on it.
Relatively complicated account creation: Compared to the straightforward process of creating an account offered by most mobile messengers, this app's registration process seems old school, requiring a username, display name, and password. If you've become accustomed to validation-code-and-phone-number-based account creation, you may find this app's sign-up process somewhat tedious, especially if all the usernames you're trying to use are already taken.
No log-out button: To use a different Kik Messenger account, you have to "reset" the app, which means you'll lose all of your conversation history. A quick way to log out and in should be implemented.
Kik Messenger makes amends for its clumsy account handling with its integrated Web browser. The app also scores good points for its snappy performance and small app size. If you enjoy text-based messaging apps, you should try this one.
