I wrote my own artisanal android app to help me with coloring based on the Hero Journey novel structure and automatically counting the daily words for Nano reporting. Otherwise it looks like a basic, buggy, no frills chapter/scene 20th century YWriter style app .

I also have a little "prompt" generator along the lines of suggesting a character arc based on the enneagram. All together generates a skeleton my little android app understands.

Useful to have on my phone wherever I have little time to work on the novel :)
