OmniFocus3
Powerful task managers have a reputation for being impenetrable. OmniFocus 3, by comparison, is approachable despite being feature–packed. It’s a breeze to create new tasks and assign them tags. These enable you to quickly filter tasks to focus on what’s important right now. Rules–based Custom Perspectives provide further scope to fine–tune what should be shown and how. The app’s very much designed for the modern iPad, with keyboard shortcut support, and a three–pane view for the sidebar, tasks, and inspector.
