As I've posted before, Grapevine is probably the best of the single pane outlines for Android devices. The developers are very responsive, as well. My only issue with the program has been that the only export option is to export in .csv format. That's fine if your're using it as an organizer or something where each line has multiple fields. But if you are using as a straight outliner for writing and organizing text, it gets awkward. Yesterday I sent them a note about the possibility of adding an easier export option for the outline text and today they emailed back that they were coming out with an update soon and that they should be able to incorporate that suggestion. Looks like a good product will be even better!

Thanks, I missed this one. Outliner Pro is pretty good, but not for rapid fire inputting. And the other one pane Android app I looked at (NoteLynx) somehow didn't work for me. This one has limited export/import options, but at 99 cents, worth the investment, and the future looks good.

I concur re both Outlined Pro and NoteLynx. For a two-pane outliner / info manager I've come to enjoy Halna. Simple and reasonably flexible.
