To add a note, tap on any time block in the timeline. You can then enter a note that will attach to that time block only. Also, if you tap on the colored total time square at the left edge of a timer and make “Non-block time” greater than zero, a note field will appear for your non-block time as well. Detailed reports show each time block and any non-block time separately with a note for each block and for any non-block time.
