Set aside a longer block for code, writing, design, or analysis without turning the timer into a performance score. Flow keeps the countdown, current task, original music, and room-masking ambience together.

Try 50/10 for sustained desk work or 90/15 when a larger block suits the project. These are practical presets, not medical advice or a claim that one biological rhythm works for everyone.

Questions

Which deep work timer should I start with?

Choose 50/10 when you want a substantial block with a short reset. Use 90/15 only when your schedule and task support a longer session, or set a custom duration.

Is the 90-minute preset scientifically optimal for everyone?

No. It is an optional workflow preset, not a universal biological prescription. Shorten, extend, or stop a session when the work or your wellbeing calls for it.
