Craving Pizza? Just Download the App

In a move sure to thrill its laziest customers, Pizza Hut unveiled Friday its new iPhone application that allows users to order pizza without so much as dialing a number. Simply type in your order, then sit back and wait until it arrives.

For those bored with the traditional methods of ordering pizza, the app also has some unconventional tools. If you want extra sauce on your wings, for instance, you shake the phone like a bottle.

And, for those who find ordering pizza too sober a task, the app comes with a racing game named "Hut Racer."

Pizza Hut hopes the app will appeal to customers who rely on their iPhones, said Brian Niccol, Pizza Hut's chief marketing officer.

"As more of our customers are integrating the iPhone and iPod touch into their everyday lives, Pizza Hut wants to be right there with them," Niccol said in a statement. "As a longtime category leader in innovation, creating an App Store application is just one more way we are helping customers place orders in a way that best fits their mobile lifestyle."

And there are myriad other programs (apps for short) taking advantage of the growth of wireless handheld devices.

Here's a small sampling:

Hard of Hearing? Just Grab Your iPhone

People don't normally equate the iPhone with medical innovation, but with the June release of an application that doubles as a hearing aid, they may have to reconsider.

The application, which is called soundAMP, is made by Ginger Labs, a California-based software applications developer, and is available in the iTunes store for $9.99.

Though it's not an actual hearing aid, soundAMP achieves a similar effect. Users just launch the application and then plug in a pair of earphones. The application takes in sound from a microphone (be it built-in, in a headset or from elsewhere) and then amplifies and filters it.

Then you can adjust the volume to your liking with a slider on the touchscreen. You also can replay five or 30 seconds by tapping the appropriate button on the screen. Hearing aids often may be associated with the more mature, but soundAMP's developers insist their product is age neutral -- of equal value to the octogenarian hard of hearing and the college student stuck in the back of a large lecture class.

(As a caveat, if you really are losing your hearing, you should probably visit a doctor -- soundAMP may be novel, but medically certified it is not.)
