The application has been made possible by the addition of APIs in Mango that allow developers access to the Contact database.
To get the most out of this app it make sense to pin it to the Start screen of your phone. The level if integration is necessarily limited, but for those missing smart dial functionality, this application will be very welcome. It is available in the marketplace for £1.29 / €1.49 / $1.49.

One of the most missed features in Windows Phone is the "Smart Dial". If you are coming from old windows mobile or other OS that enables smart dialing, you must be missing this neat feature. This application is just made to complement your phone experience with such a neat feature.
