But how does it know? The app analyzes price fluctuations while aggregating news and rumors. This strategy is less than precise, but it could save you a bit of money from time to time.

There are no guarantees. Although it claims to have a "crystal ball," Decide will not refund you for bad suggestions.

Use Decide to track pricing expectations for electronics and appliances. It says to hold off on that Sunpentown air conditioner. Its cost is cooling (sorry, I couldn't resist!).

The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 4.3 or later.

SaleSorter

There are so many great deals online, but sometimes it's best to try things on. (Warning. That size zero isn't the same everywhere). Use the Foursquare-powered SaleSorter, to find which brick-and-mortar stores are offering the best buys.

This app tells me things are 50% off at the nearest Lane Bryant . If they're not a good fit for you, there's 60% off at The Gap (GPS) around the corner. If you're too busy to make it there today, check the "notify" box on your favorite stores. SaleSorter will tell you when they're offering discounts again.

Use technology to help you shop the old way.

The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 5.1 or later.

Shopkick

Just window shopping? You'll get a kick out of this. Even if you don't buy anything, Shopkick will reward you for just stopping by.

Earn "kicks," or points, by walking into Best Buy (BBY) . Making purchases will get you more. If you accumulate enough of them, that TV will be free. Shopkick even offers gift certificates for Tiffany & Co. (TIF) . But that's at 75,000 kicks, which would involve you walking in and out American Eagle Outfitters (AEO) 3,750 times. Talk about a kickback.

The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 4.3 or later. It's available for Android as well.

Pose

Now that you've made all those purchases, it's time to show them off! Pose is a social media app that allows you to showcase your style.

Those Louboutins might hide behind your desk all day, but with Pose, your friends will still get to see them. Snap a photo and show your followers what you're wearing. If they like it, they'll click on the heart to show you the love. They can also use the app to buy your style. Imitation is the best form of flattery, right?

If you're unsure about your fashion choices, use Pose to test your outfit before wearing it out. Once your inbox is filled with compliments, your confidence will glow brighter than your fluorescent gown.
