Today's iPhone apps include Ragdoll Blaster, MeasureCam, BNO News, and MySalary. Ragdoll Blaster is a new physics based puzzler that can keep you entertained for days (the recent update added 30 more levels). MeasureCam, while perhaps not as accurate as a tape measure, can tell you the dimensions of an object based on a "virtual ruler" comparison. BNO News uses 3.0's Push Notification functionality to keep you in touch with the breaking news from all around the world. MySalary will tell you exactly how much you make (it even considers overtime and taxes). If the values MySalary spits out depress you, don't blame the developers (or us).
MeasureCam allows you to measure stuff by taking a photo and using the "virtual ruler" to measure it. What's the virtual ruler? Your finger, a dollar, a business card, or a CD/DVD. Simply take a photo with your finger (or other item) pressed flat against the object you're trying to measure. Identify which measuring item you're using, and you can then get the dimensions of anything on the "same plane" as the item. It's not quite exact, but it's the idea that interested me. I can see this getting much better with future updates.
BNO is all about breaking news. The app, which has just been updated to a new version, now does a spectacularly useful task: it uses Push Notification to get you breaking news. That means that even when your phone is off, you'll be informed of the news stories that BNO qualifies as very important. In the settings menu you can alter what kind of news you want pushed to your iPhone. If you like to be informed about what's going on in the world (aka if you're a human being) then it's worth the $2 bucks.
