I love OmniFocus. I have it on all my Apple devices. It really is a great task manager, but dont waste your money if you are willing to invest some time into a system that will work for you. Ive tried several times to get OmniFocus to work for me through different research of GTD. Definitely takes some trial and error to find your right style but once you do it is incredible how productive you can be. OmniFocus really works well for me.
