Marc Kastner reviews OmniFocus 3 for iOS beta in My thoughts on OmniFocus 2 versus 3:

OmniFocus 3 is a great successor to an already great app. The newly updated design makes it more visually pleasing.

Especially on the iPad, the new updates feels a gigantic leap. It comes much closer to the Mac, when relying on it in daily life; for example if you don’t have access to a Mac at work.
