iMessage vs. Field of 3rd Party Apps
Messaging is fast becoming the preferred way of communicating with friends and colleagues. You could argue that messaging has replaced making calls as the dominant communications app on the iPhone. Apple's native app, Messages, includes iMessage for unlimited texting with other iPhones. Other messaging apps include Kik Messenger and Whatsapp. Messages has the added advantage of being integrated into iOS and can be accessed by Apple voice-enabled artificial intelligence engine Siri.
