To help you manage your day, you will be able to view the List time and End time right at the top of the main list screen.
If you want to see the list time and end time for only some of your tasks, move the little stopwatch (we call it the Time Divider, located just above the 'add task' button) up and down - this will capture the tasks above it so will change the times accordingly.
You also can toggle ON our Start and End Time feature which will show you the start and end time for each individual task.
