Created by some characters with a shady rep themselves, the DateCheck by Intelius is a new iPhone app whose "Sleaze Detector" feature helps you do a background check on your date. (Sounds like a promising start for a relationship, no?)
Using your date's name, email address, or phone number, you can see if he has a criminal record, what his net worth is, whether or not he's living with his parents, and the usual Facebook and Twitter info.
The app is free — but the services they connect you to aren't. A criminal background check is about $19.95, for example, and finding out your date's social networking info is $9.95. Wow. A girl can never be too careful, but is this going too far?
