The only limit, really, in writing an app to bring your company directly to your customers – and vice versa – is your imagination regarding what you can do for them and how you can draw them in and keep them in.
By 2015 there will be more people in this country accessing the Internet by mobile devices like smartphones and iPads than by desk top computer. This includes your customers.
Your customers need auto-dial number for your business on their phone, a menu on your messaging system that gave them your weekly specials or access to scheduling and paying for appointments.
An iPhone/Android App can do all that and so much more, specifically for your business. An app can provide a direct, exclusive conduit between you and your customers.
The enhancements that can populate your app for the efficiency and entertainment of your customers are almost endless: video and audio, e-mail, voice recorders, calculators (mortgage, tip, scientific), you name it.
It can literally lead customers to your physical address with the GPS guidance system built into their phone or iPad. They can post a like for your Facebook page or tweeting about your wonderful service and merchandise. And to reward that loyalty, you can provide them with mobile coupons, and an integrated mobile shopping cart for in-app purchases.
