Krispy Kreme wants to give you and a friend free doughnuts.

Using the Foursquare app, check in at a Krispy Kreme shop this Wednesday, May 15, and you and a friend will each get a free Key Lime doughnut. Your choice of cake or filled.

Check in again on Wednesday, May 22, and you'll score more free doughnuts.

The following North Carolina locations are participating:

Healthcare professionals face a number of challenges while trying to provide the best they care they can. Among them is the language barrier with the large and growing spanish speaking population. There is a clever app developed at Duke to help bridge the communication gap.

UPDATE: Since I first wrote about Ibotta last November, the app has made big changes worthy of an update. Once exclusive to the iPhone, Ibotta is now available to Android users. And once limited to Target, Walmart and Walgreens, Ibotta users can now cash in at dozens of more retailers. In the Triangle, you're now also able to use Ibotta at CVS, Rite Aid, Kroger and the store I'm most excited about: Harris Teeter. And remember, the coolest feature of Ibotta is that you can use its digital coupons along with paper coupons to save even more.

If you want to trim your grocery budget, but don't have the time or inclination to clip coupons, you're in luck. There's now an app for that.

Called Ibotta, the iPhone app is aimed at tech-savvy bargain hunters looking to save a little cash on their supermarket purchases.

Instead of clipping paper coupons, Ibotta users collect their discounts by playing with their smartphones.

So far, three of the biggest American retailers have signed on to allow their customers to use Ibotta: Target, Walgreens and Walmart.

The discounts are similar to paper coupons -- 25 cents here and 75 cents there.

But instead of using a scissors to clip....

If you shop at Walmart and have a smartphone, you might want to give Jingit a try.

Instead of spending money, you can walk out of the store making money after scanning a few barcodes and taking mini surveys using the Jingit smartphone app.

You won't get rich using Jingit, but it will give you a little cash for extras that don't normally fit in your budget.

Or as Chris Ohlsen, a vice president at Jingit, told me: "You're not going to be paying your mortgage...but a lot of people look at it as fun money."

Jingit has a $15 per week cap on earnings right now, but a quick Internet search showed most Jingit users report earning about $5 per week.

I'm bumping this up to the top because it's such a fun and great deal. It's good through Oct. 5.

Here's a deal that will score you major points in the friendship department.

Using the gift-giving app Treater, you can send a favorite person a Pumpkin Spice Latte from Starbucks.

The regular price for a Pumpkin Spice Latte: $6.

Your price: FREE.

Here's how the deal, which is valid through Oct. 5, works:

If you spend any amount of time on Facebook, you most likely have dozens, if not hundreds, of photos on your page.

But few of those pictures, if any, ever get printed.

Walgreens is hoping to change that with a new Facebook photo app it launched today that not only prints your Facebook photos buy also gives you the option of printing a photo caption along with your Facebook friends' comments.

Through Sept. 1, Walgreens is hoping to hook you on the concept with a generous freebie -- up to five prints free.  After that, the 5x7 photos will cost you $2.99 each.

Smart Source -- a familiar name to generations of coupon clippers -- has gone mobile.

Long a staple of the Sunday newspaper experience, Smart Source coupons are now available on the iPad. No scissors required.

Called SmartSource Xpress, the app provides "magazines" of coupons for folks to page through, simulating that traditional Sunday morning experience.

But that's where the similarities end.

If you have a smartphone, be sure to read my story on FREEquents, a new app that rewards you for your loyalty to local businesses.

In essence, FREEquents is a punch card gone mobile, meaning you will no longer have to worry about keeping track off all those half-punched cards floating around the bottom of your purse or desk drawer.

FREEquents, developed by a Holly Springs man, hopes to expand nationwide.

Big news, Target shoppers.

The Minneapolis-based retailer announced this week that it has teamed up with shopkick to offer customers rewards using their smartphones.

Target is the largest retailer to join forces with the smartphone rewards program, which already has affiliations with Best Buy and Old Navy, among others.

Shoppers can participate in the shopkick rewards program by downloading the app to their smartphones. Versions are available free for the iPhone and Android.

Customers earn "kicks" or points, which can be redeemed for gift cards, movie tickets, Facebook credits, iTunes downloads, donations to charity and other prizes.

Harris Teeter launched a new version of its mobile shopping app this week.

Similar to the old version, you can shop the sales circular on your smartphone to create a personalized shopping list. But you can now access your e-VIC offers and save digital coupons to your loyalty card through your phone.

The new app also allows you to scan the barcode of an item in your kitchen pantry and add it to your shopping list, transfer or renew a prescription and create your own personal list of favorites that you buy on a regular basis.
