If you activate the app's Sleaze Detector, it scans criminal records to determine if anyone with that name has been charged with drug possession, assault and battery, sex crimes, DUI and other offenses.
If you click Net Worth, it looks for information about home ownership and property value.
It can also check social networking sites, such as LinkedIn to provide employment and education information.
"Date Check is like having a private investigator in your purse," John Arnold, co-founder of Intelius and executive vice president of business development, said in a statement. "Letting a stranger into your life is a huge risk, and in the age of Internet anonymity, a simple online search isn't enough to tell you everything you need to know. "
This application, the company said, "gives singles a safer way to mingle."
But though the app itself is free, the services can cost up to $40, depending on the kind of searches that are selected.
Date Check is available for download in Apple's App store and will be available soon in Android and BlackBerry versions.
You've probably heard of the Dow, the S&P 500 and the NASDAQ 100. But try this financial index on for size: The PUMA.
To celebrate its new line of bodywear, sports clothing company PUMA launched an iPhone application earlier this month that tracks global stocks, but not in the way you might think.
As stocks on the Dow Jones industrial average go up and down, so does one key element on the PUMA models: their clothes.
"Think of it as an entertaining antidote to Wall Street woes," the company said in a statement. "So now if you lose your shirt, at least our models do too."
Though the application might make Federal Reserve Chairman Ben Bernanke blush, the models only undress down to their new PUMA threads. As the Dow climbs, the clothes come back on.
The PUMA application is free in Apple's App store, and the company says it can even help save consumers money. Showing the downloaded application to a PUMA sales associate can get you a 20 percent discount. That offer lasts until Nov. 8, 2009.
Smoking marijuana is known to have an adverse effect on memory and concentration, but now, thanks to a new iPhone application, even the foggiest of users should be able to locate their connection -- make that medicinal marijuana provider -- with relative ease.
Launched by AJNAG (Activists Justifying the Natural Agriculture of Ganja), a Web-based community advocating for medical marijuana, the Cannabis app takes those seeking medicinal marijuana through the entire process of obtaining it. The app is downloadable from Apple's store for $2.99.
"Our goal is to put the power of cannabis change in your pocket while you enjoy the most sticky and potent iPhone application available!" the founders say in a statement on their Web site.
Here's how it works. The application displays an interactive map dotted with doctors who can prescribe medicinal marijuana treatment for their patients.
It also shows -- after, presumably, users have procured prescriptions -- the medicinal marijuana suppliers within the users' vicinity. And, what's more, the application includes a database of lawyers who specialize in marijuana-related cases, in should users encounter skeptical local authorities.
