The text you just received is from -- yes, this is its real name -- Booty Caller. The app is free, offered by a parenting Web site called BabyCenter.com.
Do you really want a text to remind you this might be a good time for sex? It may not be your idea of spontaneous fun, but its makers say it may well help you squeeze some fun -- and a new baby as well -- into an overscheduled life.
"Booty Caller is definitely a sign of the times," Linda Murray, the editor-in-chief of BabyCenter.com, wrote in an e-mail. Her site, she said, "set out to create a tool that would provide fertility information as well as tips on getting pregnant in fun, digestible text messages."
Look around -- through magazines, at store displays, on kids' T-shirts -- and you may see small, square black-and-white patches that remind you of bar codes. They serve much the same purpose. The idea comes from Scanbuy, a New York firm that hopes the little so-called EZcodes will become ubiquitous.
"We've been at it for a while," said Jonathan Bulkeley, the CEO of Scanbuy Inc., "and the idea's been the same: making it easier for you to navigate using the camera on your phone, instead of the keypad on your phone."
Point your camera phone at, say, an ad for running shoes, and your phone's screen will quickly show you a Web site with specs and user reviews. Point the phone at the code on a kid's shirt, and you're directed straight to his or her Facebook page.
Bulkeley said he can see countless other uses: How about a marker, for instance, on the wrapper for a head of lettuce that tells you how long ago it was picked from the field? He has even seen a code on a grave marker that lets you read about the life of the person to whom you're paying respects.
Picture yourself in the store, intrigued by the pair of running shoes you checked out via Scanbuy. But can you afford them?
Financer is a portable electronic ledger, a way for you to keep track of your money, no matter where you are.
"Financer is one of our most popular applications; and we've seen an increase in demand since the recession," said David Becker, CEO of its maker, dBelement.
The screen of your iPhone takes on the look of a checkbook ledger, the same thing you used a generation ago, except that it does the math for you.
Your account's a bit thin; maybe you'd better hold off on the shoes.
So you can't afford those Nikes? For $1.99 (a lot of these programs have similar prices at the Apple App Store), iFitness will suggest workout routines to keep you in shape. Flabby arms? Touch "arms" on the menu and find the best exercises. Worried about your abs? The program will suggest a routine.
It will also keep you honest. You can keep a log of what you've done, get an idea of your progress and, if you don't like it, you can try Fit Phone.
Or, if you're like so many of us when it comes to New Year's resolutions, you can stop and feel guilty.
