Your customers want apps that make their lives easier. They don't want to download an app just to get your current coupons. The Starbucks app, for example, lets you order online, find a Starbucks near you, save your favorite custom drinks, collect and track rewards points, and store a digital gift card. It's designed to make it as easy as possible for you to choose Starbucks for your next latte.In thinking about an app, choose a problem or inconvenience your customers have. Then find a way your app can solve that issue.
