Writing.Com General Discussion

Scrivener is about $40 and is designed to hold your notes and organize your writing work, along with the actual manuscript. it's a bit of a learning curve I am told. Apparently there is an iOS app for it.

I use a spreadsheet for my book. A tab for characters, links, history/timeline, language phrases, spells (so I use the same casting phrase), locations

It's not perfect, but it's easy because I know spreadsheets and organizing info by row/column is simple.

I work in Google Docs, so all my material is in the cloud, backed up, not in my house that could be burned down or broken into.
GD mobile only seems to do word processor documents (not spreadsheets) on iOS. Couldn't say what Android offers.
