Smart phones, like the iPhone, have created a brand new digital market for mobile applications. Developers find ways to build software that uses the built-in features of smart phones, such as internet access, GPS tracking and advanced computing abilities. This market has blown up over the last few years and the amount of applications to choose from can be overwhelming. Below, you can find a few of the best iOS applications for the iPhone.

FaceTime

FaceTime is a very popular, inexpensive app that allows users to connect with other Apple users. The application only costs $0.99 and uses the iPhone’s built-in camera and internet connection to create a clear video chat image in real time. Phones have always been a great method of long-distance communication, and with smart phone technology, people are no longer limited to voice chat. Video chat with FaceTime is the closest thing to being in the same room with someone, allowing eye contact and body language to be communicated. The app is compatible with the iPhone 4, iPad 2, iPod touch and Mac PCs.

Garmin Training Center

The Garmin Training Center is a free fitness application for the iPhone. The app uses the iPhone’s built-in GPS tracking technology to track your workouts and provide real-time information about distance, pace and calories burned. Users can customize workouts with specified trails, goals and rest intervals. The app can be used for walking, running and cycling training. The GPS tracking feature also allows the user to view a map of their actual route, which can be shared on social networking sites or exported to Google Earth.

Omnifocus

At $20, it is a bit pricey for a mobile application, but Omnifocus provides tons of value. Omnifocus is an organizational application, which is based off of David Allen’s “Getting Things Done” book. The system helps users keep track of all of their tasks and projects, so they have free space in their brains to do the best work possible.
