Keep Writing

Just a wannabe writer here. I've only ever strung a few paragraphs together, maybe an essay's worth occasionally. I used to work on blog posts in Evernote and I still use it for capturing stray thoughts. I use it as a place for ideas and that's exactly what happens. I never develop the idea, I just write down another one. Years ago I used Word, but thought maybe now there are apps better suited to the writing process. What do others use for an application/ platform?
