Gotta Go? iPhone App Tells Moviegoers When to Pee

Thousands of Apps Make Hectic Life a Whole Lot Easier

Breath-Test Device for your iPod, iPhone

Perhaps one of the more ambitious app/devices out there, iBreath is a breath-test device that attaches to your iPhone or iPod.

Users blow into the iBreath and a readout of their blood-alcohol content appears on the phone's screen.

"All kinds of people are using it," said developer Don Bassler, CEO of David Steele, the iBreath's manufacturer. "Parents of kids, college students, wives for husbands, boyfriends for girlfriends. The demographic starts dubiously as low as 16, but is basically the 18 to 50 crowd."

The iBreath debuted at Christmas and, according to Bassler, the company has sold thousands of the $79.99 devices.

Of course, even though we think these seven apps can go a long way in terms of making a hectic life a bit easier, mentioning these particular apps does not necessarily constitute an endorsement of them.

Each has many competitors, and you're invited to weigh in with suggestions in our comments section. Many apps have features you will love or hate, and the only way to find out for sure is to try them for yourself.

But most of the apps are either free or very cheap, which means a barrier has been crossed. There are a million things you can now do, with very little effort, on what you used to think was only your cell phone.

Unless, of course, you prefer to do them on paper, or a computer, or even -- what a quaint idea -- in the flesh.
