I totally disagree with you, I have been writing for years, and I started my first couple of novels on an old manual typewriter. If you are a writer, then you should actually be using your computer more before you publish. As a writer you should never depend on the mobile app to write. I challenge you to write down your ideas with a pen and paper first then type it onto a manual typewriter, electric typewriter and computer. Typing via your phone and or tablet is much harder and more room for mistakes.
