ZUHD: Focus, App Blocker & AI

Make room for what matters with ZUHD: your all-in-one app for focus, app and website blocking, everyday tasks and personal progress.

FOCUS ON YOUR NEXT STEP
Start a timed session with Quick Focus and choose the duration that suits you. Create reusable profiles for work, study or your own routine. Extend an active session directly from the timer and use schedules to make space for focused time.

SET YOUR OWN BOUNDARIES
Choose the apps and websites you want to limit. Combine focus sessions, schedules and supported usage limits. The local adult-content filter contains more than 5,000,000 domain rules. Other categories include gambling, social media, games, shopping and news. Add your own rules and allowlists.

The filter works locally on your device. Domain coverage is not a count of visits blocked and cannot guarantee that every website is covered. Protection requires setup, the relevant Android permissions and trial or Premium access.

TURN TASKS INTO PROGRESS
Organize everyday tasks with Side Quests. Complete a task, earn XP and work toward your next level. Follow your focus minutes, completed sessions and personal trends with detailed progress insights.

EXPLORE MASTERY
Build your attributes, earn badges and discover a connected path through the ranks. Unreached rewards stay hidden until you unlock them. The complete Mastery journey is available with Premium.

MOVE FORWARD TOGETHER
Connect with friends and use optional accountability features. Adults aged 18 and over can join the moderated Community and private text conversations. Reporting and blocking tools are available. Eligible accounts aged 13 and over automatically participate in the Friends and Global progress rankings within the app.

LOCAL-FIRST PRIVACY
Sensitive blocking rules, app and domain choices, screen-time details and local filtering stay on your device by default. ZUHD does not keep a complete browsing history, full URLs with search parameters, keystrokes or VPN traffic logs. Optional account and social features use the data needed to provide those features.

ACCESSIBILITY SERVICE (AccessibilityService API)
With your consent, ZUHD detects the foreground app and reads relevant visible screen information in supported apps and browsers to apply your app, website and search-term rules. It may show a block screen and invoke Home, Back or Close. Processing is on-device; screen content, inputs, passwords and full URLs are not stored or transmitted. You can disable the service in Android settings. The separate local VPN filters domains without decrypting HTTPS or changing your location.

FREE AND PREMIUM
After the three-day trial, Free keeps Home, Side Quests and basic Focus with up to three saved profiles and three active time windows. Free may show ads. Premium adds full protection, detailed progress, complete Mastery, expanded focus options and an ad-free experience. Access also depends on age eligibility.

Protection depends on your permissions, supported apps and browsers, Android restrictions and device behavior. ZUHD adds practical boundaries; it does not promise an unbreakable block.

Start with one task. Make time for what matters.

NSFW AI BLOCKING
NSFW AI detects adult content in visible images and text and can block it with a block screen. Analysis takes place locally on your device. Images and text are processed temporarily in memory and are not saved or transmitted. Requires Android 14 or later, your consent and the necessary Android Accessibility permissions.
