Why not a web app that is responsive so it can be used on mobile or in a desktop browser? I can't speak for all developers, but I would hate to be forced to us

Why not a web app that is responsive so it can be used on mobile or in a desktop browser? I can't speak for all developers, but I would hate to be forced to use my issue tracker on an iOS device (really any mobile/touch device). Mainly because at times I want to add code snippets, text is harder to type on touch, things like that. edit: I see after reading some of the other comments that other platforms are planned. I would still question the logic of building applications rather than a web application though.
