About this app

TiedSiren is a strict app blocker and website blocker for Android. You pick what distracts you, you set the timer, and TiedSiren holds the line. Not even you can override it.

Once a blocking session is running, there is no way to end it early from the app. No pause, no panic button, no exceptions. You wait it out. You set the rules when you're strong; TiedSiren holds them when you're not.

WHAT YOU CAN BLOCK
• Social media: TikTok, Instagram, YouTube, X, Reddit, Snapchat
• Any Android app: games, news, shopping, whatever eats your evenings
• Websites too: block the site, not just the app, so your browser is not a side door
• Block TikTok during exam season, block Instagram after midnight, block YouTube at work. You decide the rules.

HOW IT WORKS
• Build blocklists of apps and websites: study, deep work, sleep
• Start a focus session now, or schedule recurring ones (work hours, evenings, sleep time)
• Strict Mode locks your session: it cannot be ended early from the app, you wait it out
• Blocked apps show a blocking screen; blocked websites are closed the moment they open

FOCUS, NOT GAMIFICATION
No streaks to lose, no badges, no guilt trips. TiedSiren is a doomscrolling blocker that cuts screen time by removing the choice in the moment, not by shaming you after it. Less scrolling, less brainrot, more of your evening back.

WHO IT IS FOR
• Students who open TikTok instead of their notes and lose the night to doomscrolling
• People working from home who need deep focus, not a distraction every ten minutes
• Everyone whose self-control works fine at 9 a.m. and disappears at 11 p.m.

If you have quit every app blocker because you could, this one is built for you. A screen time app you can talk your way out of is a suggestion, not a decision.

TiedSiren doesn't judge. It just holds the line. The tied siren in our logo is the whole idea: temptation, restrained.

WHY TIEDSIREN USES THE ACCESSIBILITY PERMISSION (AccessibilityService API)
TiedSiren uses Android's AccessibilityService API to enforce your blocklist during an active blocking session. It detects (1) the package name of the app currently in the foreground, and (2) the web address shown in your browser's address bar, so it can display a blocking screen when you open a blocked app, or send you back when you navigate to a blocked website.
- What is accessed: the foreground app's package name, and — only during an active session — the web address (URL) shown in your browser's address bar.
- What is NOT accessed: the contents of your messages, emails, documents, photos, passwords, or other form fields. TiedSiren reads only the browser address bar, solely to compare it against the websites you chose to block.
- Data handling: everything is processed in real time on your device to enforce your own blocklist — never stored, logged, or transmitted.
You enable this permission yourself after an in-app explanation, and you can turn it off at any time in Android Settings → Accessibility. TiedSiren is not an accessibility tool for people with disabilities; it uses this API because it is the only reliable way to detect and block distracting apps and websites the moment they open.

Your 11 p.m. self will hate it. Tomorrow-you won't.
