Block distractions. Start with 15, 25 or 50 minutes. Use quick focus, breaks, daily goals and session history. Add automatic schedules with Pro.
Make room for the task in front of you. ZenMaru blocks distracting apps while you work, study or read, with a calm design and Maru by your side.
FREE TO START
• Choose apps, categories and websites to block.
• Start a 15, 25 or 50-minute session; adjust from 15 to 180 minutes.
• Write down what you want to focus on.
• Solve 3 math questions for a 1–15 minute temporary unlock.
• Set a daily goal and view your last 7 days, session history and streak.
After a break, blocking resumes while an active session or rule still applies.
ZENMARU PRO
A monthly auto-renewing subscription adds automatic blocking schedules, with work, study and evening templates. Check pricing and terms before purchase. Manage your subscription in the App Store.
RECORDS YOU CAN UNDERSTAND
Focus time is manual timer time minus breaks, including sessions ended early. It is not a measure of reduced screen time. Automatic schedules are not counted.
Settings and records stay on your device. No ads or external analytics SDKs. Blocking requires Apple Screen Time permission. New focus screens are available in English and Japanese.
