Is there a way to automatically save a journal entry, rather than having to click save each time. As a couple of times when adding a few captions to photos  or adding a few paragraphs, my internet disappears and I lose all my work.

Joel, we've had that happen because of sketchy internet (not on CycleBlaze), and started writing our entries as a separate file, whether some kind of text-editing program or google documents or what-have-you. I know it adds another step to the process but I do kind of like having each entry saved in a purely text form, like pages in a book. 

Already writing my journal on notes on my iPhone. Was more about when adding photos 

That's what I do.  Write it up off line and paste it in.  This also helps on days without internet.  It enables you to write each day as it happens and paste it all in later.
