To be fair, there was only one note that I wanted to hang on to: the planning and thoughts around something I've been working on for a while. I say working but I really mean putting off again and again, adding little bits to it here and there to convince myself I was still serious about it.
Maybe I just have to be pragmatic, anything else in the app was either an archive or very probably something I wasn't actually going to use or I would have by now. Perhaps an enforced clear out will cause me to refocus on something that I will work on.
In light of the calamitous failure of One Jotter I've decided to switch to another app. I don't really get on with Pure Writer anymore so have opted for iA Writer synced straight to Dropbox.
My subscription runs to August next year there's no issue on that front and, who knows, they may have improved the WordPress integration in that time.
I'll be treating iA Writer just as I have any other app: copying the text manually or sharing it to the WordPress app. I just want to ensure there won't be another issue like earlier today.
