The Power of 4 Quadrants The Matrix forces you to categorize your life into four simple, high-contrast zones: - Do It (Green): Tasks you want to do and should do. The "Action" zone. - Push Through (Yellow): Essential long-term tasks that require grit. - Drop It (Blue): Busy work that feels productive but isn't. Delete it. - Resist It (Red): The sirens of procrastination. Resist the urge. Zero Bloat: No ads, no unnecessary pings, no complexity. Just clarity. Built in Focus Mode with Pomodoro Timer, Lo-Fi Music, and Fun Themes.

Nook is a quiet corner for focused work. Set a timer, work in short bursts, and take real breaks in between. No character to feed, no leaderboard to climb, no streak shaming you for a day off. Just the time you gave to the thing you were doing. COMPLETELY FREE No trial countdown. No subscription. No paywall. No ads. There is nothing to buy in Nook, now or ever. FOCUS TIMER Work, short break and long break lengths are all yours to set. A breathing ring marks the session so you can tell at a glance where you are without reading numbers. Pause, skip a phase, or stop whenever you need to. STOPWATCH When 25 minutes is the wrong shape, count up instead. Take laps to mark stages inside one long stretch. Stopping saves the session to your history like any other. YOUR HISTORY See any day, week or month. A chart shows when you actually focused, and every session is listed with its start and end time. Plain numbers, no scores. OPTIONAL GOALS Daily, weekly and monthly session targets, off unless you switch them on. Missing one does nothing at all. GENTLE REMINDERS Pick the days and times you want to be nudged. Nook says something short and encouraging, then leaves you alone. MADE TO STAY OUT OF THE WAY Six alarm tones to choose from, or none. Light, dark, or follow the system. A quiet accent colour if you want one. Haptics you can switch off. Breaks that start on their own, or wait for you. PRIVATE BY DESIGN No account. No sign-in. No analytics. Everything you enter stays on your device. Nook has no server to send it to. Nook is for students, for people with ADHD who need a timer that does not nag, and for anyone who just wants a calm place to put their attention for a while.
