ClarusTasks is a powerful task management app for Windows Phone, based on David Allen’s GTD methodology. ClarusTasks is available on the Windows Phone App Store here.
The Home page is always available via the app bar icon and allows access to the inbox, projects, contexts, flagged items and settings.
The NEXT screen displays the next action to complete, actions based on when they are due. Tasks can also be grouped by project or context.
Pinch the screen anywhere in the app to quickly add tasks to the INBOX. Tasks in the INBOX can be later categorized into projects and contexts.
ClarusTasks includes extensive search options and allows one to filter data on date, project, context, status and more.
