I really like to use Habitica as a to-do list, because it gamifies all my tasks. It does not integrate with Outlook, though. Outlook’s own app is also worth trying if you use those tasks a lot and create tasks from your inbox. Toggl is great for tracking time. And for a new way of working, try a Kanban board like Trello. This helps you create a workflow. Read up on Kanban techniques first!
