What is a good alternative to the 30/30 app? That was so good at visually helping to see the total time all tasks in a day would take and indicating what time your list would end?

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!
