PLEASE, no comments about not needing auto next action. I have had that discussion. I run multiple projects and am really dependent on the function. Otherwise I will spend too much time fiddling with setting up my next action, rather than letting software do it for me.
I'm not 100% sure but I think NirvanaHQ does auto next actions in Projects. It's a web-based system but is light years ahead of Toodledo because it's been designed specifically for GTD. Projects can be set to sequential or parallel, active/inactive.

They have no native mobile client yet but are about to release their first iOS version (it's been in beta for at least a few months). They say that Android will follow soon after but in any case, they have a very workable mobile web version that I've tried on iOS and it's pretty good.
