When it comes to going off the laptop and onto mobile devices, writing and putting together a novel can be a little tricky when it comes time to synchronise the content. The ability to export all your stuff back to laptop mode is the functionality you want.
Note-taking and writing platforms have been already covered here:
Below are the most useful apps available for Android and Apple for structuring and planning out your story.
Pluot is purely a character and story planning app for writers.
It allows you to build plot scenes which you can reorder through drag-and-drop, develop characters with profiles and attributes, create locations, construct plotlines and link them up, and add images.
And once you’re ready to write you can export your outlines to text files.
Novelist is a writing assistant that will help plan out your novel from a nascent stage into a published book. I give you the ability to brainstorm, add research, develop characters, and outline every aspect of the story.
It’s even got a web interface application that can help you stay on the platform and continue writing multiple drafts till the finished book.
Most important of all, you can export to epub, odt, and HTML.
Web-browser based Wavemaker runs on virtually anything. It works offline or it can be installed and run on any device, allowing you to sync your devices up using google drive.
You can plan and structure your book into chapters, scenes, and make notes.
Export as Word (DocX)
There a planning board and data base function as well as a snowflake tool.
Export as HTM (.html) for sharing to the web, creating e-book or for openning with Word.
Export is also avdilable for Markdown (.md), Word (.docx), ePub (.epub) and Rich Text Format (.rtf)
All three are practical enough to get your project fleshed out from idea to complete novel, and if you want to move to a fifteenth platform they each have yhst all important export facility.
