This thesis is based on a personal project, Estream. The aim was to build an improved multiplatform mobile application based on the feedback received on a prototype version.

The thesis describes the development steps of a multiplatform mobile applica-tion based on competitive E-sports and the streaming of games. Firstly, an online survey is conducted to gather initial information. Secondly, a previously made prototype will be put on the Android app store to gather feedback. Lastly, both the online survey and the prototype feedback will be studied and they form the basis for the development of the improved multiplatform application.

The prototype has been distributed and feedback was gathered. With the use of this feedback the first Estream version was created. Estream is now a multi-platform mobile application ready for distribution.
