App MD: 5 smart phone apps that could save you a trip to the doctor

Odds are, your smart phone is full of apps to help you live your life: games, task management, e-mail and more. You may even have an application like WebMD, but did you know there are other medical apps on the market, or coming soon, that might save you a trip to the doctor's office?

Thanks to increasingly sensitive sensors on smart phones, developers are able to create apps to diagnose what ails you and even figure out what prescription you need. In addition to helping you cut out a doctor visit, these apps may also help an aid worker bring medical care to people living in impoverished areas, without the need for an on-site physician or expensive and difficult-to-transport equipment.

These first three apps can be downloaded today to help you determine if an office visit is necessary; the last two are on the horizon.
