  A wealth of mobile apps are helping shoppers  find the merchandise they want at the lowest prices available—whether in  bricks-and-mortar stores or online—rack up redeemable points, find  fleeting special deals and collect coupons.
   "I've had quite a bit of savings by using apps," says graphic  designer Armand Davila, 41. The Sarasota, Fla., resident uses two or  three mobile-phone applications to compare prices. "There's no reason  not to bring your phone with you to the store, because you just might  find out that you've been overpaying for something that's cheaper right  down the street," he says.
   There are dozens of apps that compare prices using bar-code-scanning  technology, including an eponymous app from TheFind Inc.; PriceGrabber,  which Experian PLC agreed in May to sell to Ybrand Digital Ltd.;  Pic2Shop from Vision Smarts, and the aptly named Barcode Scanner from  ZXing Team, all free. 
   The idea is simple: Aim your phone's camera at an item's bar code and  the app tells you whether you can get it cheaper at nearby stores or  online.

  Mr. Davila says that while hunting for  an office chair he recently left an Office Depot store because the  ShopSavvy bar-code-scanning app on his mobile phone found the same chair  for about $20 less at a nearby Target store. He ended up buying a  higher-quality chair at Target for the same amount he would have spent  on the lesser chair at Office Depot.
   ShopSavvy Inc.'s app and another of the more popular bar-code-scanning apps,  eBay Inc.'s    EBAY +0.63%  RedLaser—both free—are among those that not only allow shoppers to  check prices, but also make it easy to purchase items from select  websites using your phone. With  Amazon.com Inc.'s    AMZN +1.88%  free Price Check app, you can compare the company's prices to those at  other retailers by scanning bar codes, taking photos of products or  entering voice or text searches. If it turns out Amazon has the best  buy, you can also make the purchase through the app.
  Love Those PointsPlenty  of apps dole out rewards to shoppers. The free LevelUp app, from SCVNGR  Inc., is one of several that give shoppers cash credits after they  spend a certain amount using the app at selected retailers.

  Shoppers can also use a variety of apps  to earn cash or other rewards without even making a purchase. When you  scan a bar code with the Smoopa app, free from Smoopa Inc., and enter  the price of the item and the location of the store, it shows you  comparison prices and sometimes gives you a bonus—a credit that can be  redeemed in cash or applied to gift cards or charitable donations.
    An app called Shopkick, free from Shopkick Inc., rewards customers  with points, called kicks, just for entering participating stores, in  addition to helping them find the cheapest prices at area retailers.  Users of the app also accrue kicks when they buy items in-store. The  points can be redeemed for discounts at a list of retailers including  Old Navy and American Eagle Outfitters. Shopkick also doles out extra  points on some days to users who visit certain malls.

  Joanna Alva, 23, a paralegal from  Sunnyvale, Calif., says she checks Shopkick twice a day for discounts  and sometimes goes to the mall just to get the extra kicks. "It's a lot  more fun than sitting at a computer" searching for bargains, says Ms.  Alva. "I've found myself going out of my way" to get points.
   Special DealsFor shoppers seeking more serendipity, the  Groupon Now! app gathers limited-time offers near a user's location. New  York-based magazine editor Jamilah Lemieux, 27, says she checks the  free app from Groupon Inc. every day before she leaves her apartment in  hopes of finding an unusual deal, such as the hair trim and conditioning  she recently paid $19 for.

  Other free apps aggregate online  discounts, such as Coupon Sherpa from Capable Ant for Apple and Android  devices, RetailMeNot from WhaleShark Media Inc. for Apple devices only,  and CoupSource from CoupSource Inc. for Android only. Surfwax Media Inc.  makes free coupon apps called TapSave for Android devices and Coupon  Closet for Apple devices. 
   There is also an app for those forgetful shoppers who leave their  supermarket, drugstore and other loyalty cards at home or in the car.  The free Key Ring app, from Mobestream Media Inc., stores that  information in a mobile phone for easy access at checkout.
   As always, more is on the way. For one thing, with all this shopping  power in the hands of consumers, retailers "will have to develop apps of  their own that work to their advantage," says Sucharita Mulpuru, a  Forrester Research Inc. analyst. That could include more apps that offer  discounts to put a retailer at the top of shoppers' lists. "Over time,"  says Ms. Mulpuru, "that could turn this whole market on its head  again."
