"The Core powers mobi sites, allowing fast and cost-effective creation of interactive online information sites accessed via mobile phones. These sites can offer multimedia content, information and entertainment to users in a way similar to if they install an application on their handset… but without the hassle or compatibility niggles. Unlike apps specifically created for the iPhone, Android or other smartphones, a mobi site is device-independent – it can be used by almost any modern phone that has a Web browser. Clever techniques in delivering sites via mobile phone browser means mobie developers can deliver the same (or better) user experience, but faster, more cheaply and more flexibly than through apps."
