With spring on the horizon but record-breaking cold temperatures still ravaging parts of the country, everyone—especially travelers caught by a surprise storm or frigid temps—is doing what they can to stay warm.

While most people temper the bitter chill by adding multiple layers to their outerwear—that seems reasonable, no?—for some, that is apparently not enough. Enter iTunes App Store.

I know what you're thinking. How can an iPhone app possibly help keep me warm? Mashable reviewed an app that claims to be able to turn your phone into a hand-warming device. How does "Pocket Heater" work?

The app works by stressing the iPhone's processor, battery and other functions to cause the device to overheat and hence become warm to the touch. In theory, this stressing shouldn't cause any damage to the device or yourself, but this is still something we'd classify as "no warranty, use at your own peril."

Not exactly resounding praise, but still intriguing nonetheless. After knowing how it works, the next logical question is: Does it work? Says Mashable:

The verdict? It works...sort of. It takes some time for the app to heat the device up, and while you certainly get a warming effect, I'm not sure it's anything that would actually negate the cold.

So while you'll probably want to stick to just wearing insulated winter-ready garments, there's no denying the cool factor of this app. Want to try it out? It's only $.99 and available for download at the Apple App Store.
