Timing can become a major factor for success when designing and launching a mobile application considering location. With gasoline in some markets heading between $4 and $5 per gallon, this YP mobile app, which helps consumers find the best price, could become priceless. Based on location, the free app lets users customize their searches, home screen, and content to automatically view favorites, get information at a glance, and scan for quick ratings on restaurants and other retail locations. Looking for a restaurant or have a coupon? The app integrates more than 300,000 menus. It also reminds users when a deal is about to expire.
