There is Chatty out already which i think breaks the ToA but lets you use your phone to chat directly in game. There already is ffxiv guide which has a database of recipies but its now getting outdated, there is at least 2 clocks out there which show the moon phase/leve reset. I started a leve time myself just after release but discovered that I was already beaten to it. Do your research to discover what is out there what needs to be improved and do your best, let us know what you come up with.
