Allrecipes, the operator of food-focused social-networking website Allrecipes.com, has boosted the rate of downloads and use of its Dinner Spinner app by 50 percent in northern Ohio, where it hasinstalled Bluetooth beacons within 58 Marc’sstores. A beacon, provided by Footmarks, is mounted at the entrance to every Marc’s store, where it transmits a unique ID number that aDinner Spinner user’s smartphone receives when he or she enters the store. The app then uses that ID to determine that shopper’s store location, and to access local weather and product promotioninformation. Based on that data, the app displays recommended recipes, along with a list of ingredients. Versions of the Dinner Spinner app are availablefor IOS and Android devices.
