Brown noise is generated locally on your Mac. No need to open Spotify and fall down a playlist rabbit hole. No waiting for Wi-Fi to connect. Open your laptop and start focusing immediately.
A deep work timer is a focus tool built around long, uninterrupted sessions — the opposite of the short bursts you get with the pomodoro technique. The concept comes from Cal Newport's book Deep Work, which argues that meaningful output happens in stretches of 60 to 120 minutes of distraction-free attention.
Deep Timer is a deep work timer designed to disappear. It lives in your macOS menu bar, plays brown noise to mask distractions, and shows your remaining time as a small countdown in the corner of your screen. No notifications, no streaks, no dashboards. You pick a duration, hit start, and the timer steps out of the way.
When the session ends, a gentle alert lets you know — and the brown noise stops automatically. A deep work timer should help you focus, not become another thing to manage.
Deeper than white noise. Smoother than pink. Brown noise masks distractions and helps you sink into flow state.
Lives in your menu bar. No dock icon, no window clutter. Start a session in two clicks.
30, 60, 90, and 120-minute presets sized for real deep work sessions. One click to start.
Life interrupts. Pause your timer and brown noise, then pick up right where you left off.
An audio alert lets you know when your session is complete. Brown noise stops automatically.
Open-ended sessions. Press start, focus as long as you want, and the elapsed time runs quietly in your menu bar.
A deep work timer is a focus timer built for long, uninterrupted sessions — typically 60 to 120 minutes — based on Cal Newport's concept of deep work. Unlike pomodoro timers that break time into short 25-minute blocks, it optimizes for sinking into a single task for an extended stretch.
Cal Newport recommends starting at 60 minutes and building up to 90–120 minute sessions as your focus stamina grows. Deep Timer ships with 30, 60, 90, and 120-minute presets so you can pick whatever fits your day.
