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.

Thanks for mentioning this, I'm still looking for the best note app for me, and this looks nice for storing photos along with notes..

Since it stores to sqldb I could probably sync the db to a webserver and build a web frontend for presentation.
