I use "Note Everything" on my Android phone. I found is uses a SQLite db for storing its info. Might try this for extracting the contents if I ever want to move to Apple phone.

Just tried it. I have Note Everything save to Google Drive. Extracted that zip file, read it here, saved the text notes as csv, looked at it in txtedit. Great!!!!

Could write a gawk program to recreate the notes in directories.
