Mobile app development has come a long way since it first burst onto the scene. In this talk we’ll look at the lay of the land, focussing largely on the current landscape and the tools which are available to the modern mobile developer. As developers we currently have many different routes to realise our applications on mobile devices. From native languages, cross platform development tools such as React Native and the new “app like”, Progressive Web Apps. We’ll delve into exactly what these differing platforms are, their strengths and weaknesses and in which circumstances each may be appropriate to use.
