[O] Android org app with sync?

[Alasdair McAndrew]

I'm sure this has been asked and answered many times before, but 
I've hunted about - both on the web and on Google Play - to find 
some app which can sync with my org files.  The closest I've come 
is orgzly:

https://play.google.com/store/apps/details?id=com.orgzly

which however only syncs with Dropbox, which I don't use (I use a 
self-hosted ownCloud instead).

Are there any other apps which will allow me to update and edit 
org files on my android device, and have them sync automatically?

I guess I can probably use orgzly with a local file, and have a 
third party app sync with my ownCloud files.  Seems like extra 
fuss, though!

Thanks,
Alasdair
