Star Rover (iPhone) $0.99 (was $1.99)

Star Rover is a pretty cool app for amateur astronomers. It tracks stars, constellations, planets and moons in real time all the time, creating a virtual sky view after it determines your location using the iPhone’s GPS functionality.

The app seems to be filled with interesting information about the movements of celestial bodies, as well as tons of images. Star Rover shows nebulae, moon phases, simulated eclipses — it’s a whole lot of astronomy information in a little, one-dollar app.

Monthly Payment Calculator (iPhone) Free (was $1.99)

Big purchases can be daunting, especially when it comes to figuring out just how they’ll break up from month to month. Of course, you could always just do some fairly simple math to calculate loan interest and monthly payments. But hey, this app is free.

Monthly Payment Calculator lets you input the amount of your loan and the interest rate, plus the length of the loan, and spits out how much you’ll owe each month. All with no work on your part.

Camera Protractor Lite (iPhone) Free (was $0.99)

Okay, you might not need a protractor every day, but this was free and students will probably get some use out of it. Camera Protractor Lite is like having a virtual protractor, using your iPhone’s camera to help measure angles.

When you fire up the app, a protractor appears on the screen, overlaying it on top of whatever you’re shooting with your camera. It’s basically an augmented reality app, and is handy for math classes and similar situations — you know, whenever you might need a protractor, but forgot to bring yours from home.
