Deep work
Distraction-free sessions that block pings and hold the timer.
No pings, by default
Deep work mode blocks notifications, mutes the phone, and dims everything that isn't the timer. The room goes quiet so the work can get loud.
What it blocks
notifications off social muted phone do-not-disturb sound your bed, or none
Why it matters
Attention is the product. A two-hour deep-work session beats six hours of tab-switching every time.
