Great app, limited by lack of App Store upgrades – OmniFocus 2 (legacy support edition) Review
I have used OF on Mac and iOS since they were available. The apps from OmniGroup are *not* cheap, but they are usually worth it.
Omni's attitude of "iPad is a separate version" and then "it isn't separate anymore, but you still have to pay more money after buying both apps" does get old after awhile.
