Access org attachments from my phone?

I sync my Emacs files via Dropbox. I use org-attach to attach files to notes. I've used beorg and Orgro. They're great. But I haven't found an app that will actually access attachments. I attach images, pdfs, and audio files, and I'd love to be able to access them on-the-go on my phone.

So far, any apps I've used do a pretty good job of accessing the TEXT of files, but it just can't recognize attachments.

This tempts me to use Evernote or Apple Notes, since all attachments show up there without any hassle.

Any ideas?
