Looking to build a mobile presence, without building an app? A new DIY service called Duda Mobile lets you customize your website for a variety of mobile devices, including iPhones, Android phones, and BlackBerrys, simply by pasting in your site’s URL. You can choose from a variety of mobile website templates or use Duda’s design studio. Anytime you make changes on your regular website, the mobile version updates automatically. You can also add a map with directions to your business or a click-to-call button so customers can contact you easily. Duda also offers free analytic tools for keeping track of mobile website traffic.

The basic version of the service is free. The professional version, which includes advanced features such as click-to-call, costs $9 a month.
