Real focus needs real blocking. GRDN locks the apps that steal your attention — for a session or all day — and gives the hours back to your projects: focus sessions, tasks, tracked time, and friends who cheer you on. The mindful part is real, too. When you need back into a blocked app, GRDN doesn't fight you: breathe through a short countdown, write one thing you're grateful for, and get ten honest minutes. Then it locks again. — BLOCK THE NOISE — • Real app blocking, not reminders: Instagram, TikTok, X stay locked • Session blocking while you focus, or scheduled all-day blocking • The Gate Pause: need back in? Breathe through a short countdown, write one gratitude, and get 10 honest minutes. Then it re-locks automatically. — DO THE WORK — • Pomodoro focus timer with lock-screen Live Activities — sessions that also hard-block your apps • Tasks and projects: priorities, recurring tasks, today planning, and two-way Google Calendar sync • Time tracking built for independent workers: focus sessions land on projects automatically — tracked, billable, exportable to CSV • Friends see your focus sessions and cheer the streak • Your garden grows as you focus — every session levels it up — WHY ONE APP? — Blockers win you the hour, then abandon it. To-do apps organize the hour, but can't protect it. GRDN is the only app that does both: every blocked distraction becomes an hour you can see — planned, timed, tracked, and witnessed. — FREE TIER — Pomodoro timer, tasks, projects, and basic time tracking. Free forever. No card required. — PREMIUM — Real app blocking, the Gate Pause, scheduled all-day blocking, friends and social, lock-screen Live Activities, Google Calendar sync, extended insights and history. $3.99/month or $34.99/year with a 30-day free trial. Cancel anytime in Settings. Opal charges $99/year for similar Screen Time blocking — GRDN is one-third the price. — FOR PEOPLE WHO'VE TRIED EVERYTHING — If you've installed Forest, Freedom, Opal, Todoist, or Toggl and still can't focus, GRDN is built for you. Structure will take you where willpower can't. Terms of Use: https://www.irons.design/grdn Privacy Policy: https://www.irons.design/grdn
