ActionTree encompasses what we all need to function efficiently: Management of Projects and management of Time. Both entities are represented by separate but related views - the "Projects" view and the "Timeline" view. A tap on the view title switches between the two. The Projects view enables the user to create hierarchal projects. The Timeline view - a view of reminders and events sorted by time. In the Projects view, you can break your projects down to manageable steps that can be collapsed, expanded, fitted with quick reminders, photos and notes. The Timeline view provides list of reminders and events sorted by time. New reminders and events can be created and edited. Links are provided to correlate between the Projects and the Timeline views.
