This thesis was made for Cybercom in Ostersund. They wanted an evaluation of HTML5 cross platform applications which studied HTML5 features as well as JavaScript libraries and frameworks. The resources put into mobile application development can be reduced bymaking applications that can work on all platforms instead of only natively. These types ofapplications are called cross platform applications and can be developed with specic tools.One way to develop cross platform applications is by using HTML5, which can either beused as a web application or packed into native applications using plug-ins. The purpose ofthis thesis was to create a mobile web app that can save maps to be used oine. The workwas done by evaluating frameworks for web applications. Frameworks that provide userinterface elements and features similar to those in native applications, and libraries that render maps served by map servers. Development environments for web development were also tested and evaluated. The results of the research and development were documented experience, and a HTML5 application that shows a map, has GPS functionality and can beused oine.
