The Key Ring app from Mobestream (recently acquired by Gannett) has been around for some time now. Available for free on iOS, Android, Windows and BlackBerry, it brings all your plastic cards together. The app lets you simply scan and store your existing loyalty cards, enroll in new loyalty programs and get exclusive coupons and discounts from top retailers. But it doesn’t stop there…

Unlike Passbook, Key ring lets you link coupons to your debit or credit card and clip your grocery coupons from popular retailers digitally. And since all your loyalty cards and coupons are all digital upon scanning, just show your iPhone at checkout to redeem a coupon.

Key Ring supports digital circulars for a bunch of retailers, including Albertsons, Babies ‘R Us, Best Buy, CVS, Dick’s Sporting Goods, Giant Food, GNC, Ikea, Jewel-Osco, Kmart, Kohl’s, Lowe’s Home Improvement, Macy’s, Michaels, Office Depot, OfficeMax MaxPerks, Old Navy, Petco, PetSmart, Sears, Shopko, Smart and Final, Staples, Stop&Shop, Target, The Great Indoors, Toys ‘R Us, True Value and Walgreens.
