You can filter your tasks by due date, person, organization, workspace, app and label. Click the "Tasks" icon in the top blue bar to filter your tasks.
Or, go to your workspace, then click "[Workspacename] Tasks" to your right and get an overview of the tasks in that specific workspace.
The screenshot below is from your Podio tasks page, which is available via the top blue bar. You'll see the filtering options highlighted in green.
