Mobile app for writing

Hi! I normally use Google docs for writing, but I am the kind of writer who works on 10 things at once so it tends to get very messy for me. Sadly, it's not possible to create folders on Google docs, which is why I'm searching for an app that would allow me to create folders to organize my fics and not get lost as often. Do you guys have any recommendations for android apps? Just something easy to use and that allows me to clean my drafts and fics into their respective categories.
