Protect a proper stretch of time for demanding work
Use Flow to fence off a report, research chapter, design pass, or technical problem from the rest of a hybrid day. The task, countdown, original soundtrack, and ambient controls stay together.
A 50/10 block can preserve momentum without consuming the diary; 90/15 is available when deeper continuity is useful. Both are optional working patterns, not health advice or universal claims about concentration.
Questions
How should I fit deep work around meetings?
Choose a block that leaves a realistic margin before your next commitment. A 50/10 session is often easier to place; use a custom duration when the diary is tighter.
Does Flow claim that 90 minutes is the ideal focus cycle?
No. The 90/15 option is simply a practical preset. Individual tasks, circumstances, access needs, and energy levels call for different session lengths.
