Can i buy OO for iphone as a standalone?

iphone 4S

keen OO user. no ipad, just want to be able to update my master OO file on the go.

do i have to buy the whole iOS productivity pack, or can i get OO as standalone app?

You can buy OmniOutliner independently of the Productivity Pack, but be aware that the Universal version of OmniOutliner has not yet been released. So right now, OmniOutliner won’t run on your phone regardless of what version you buy. :)

Once the Universal update to OmniOutliner has been released, you can purchase it via the App Store by following this link: https://itunes.apple.com/us/app/omnioutliner-2/id704610906?mt=8
