TiedSiren is a strict app blocker and website blocker for Android. Block apps and websites that steal your focus: TikTok, Instagram, YouTube, Reddit, games, any app or site. Set a focus timer or a schedule, cut your screen time and get your evenings back.

📵 BLOCK APPS AND WEBSITES TOGETHER
Most app blockers stop the app, then you open the same site in your browser. TiedSiren blocks the app and its website together. Block TikTok and tiktok.com, block Instagram and instagram.com, block YouTube and youtube.com. Your browser is no longer a way around.

🔒 STRICT MODE: THE APP BLOCKER YOU CAN'T SWITCH OFF
Every app blocker works until the moment you want to scroll. Then you pause it, snooze it or delete the rule. With Strict Mode, a focus session can't be ended early from the app. No pause, no snooze, no exceptions. You decide once, when you're focused, and the block holds when you're tired. You choose when to use it.

⏱ FOCUS TIMER
Start a focus session now and choose how long it lasts. Study for two hours, work until lunch, or take a full evening off your phone.

📅 SCHEDULES THAT REPEAT
Schedule recurring blocks for work hours, study time, evenings and bedtime. Your app blocker turns on by itself, every day, with no decision to make.

📋 BLOCKLISTS FOR EVERY ROUTINE
Build blocklists for study, deep work and sleep. Social media, games, news, shopping, streaming: block distracting apps by group and reuse them anytime.

🔞 BLOCK ADDICTIVE APPS: GAMBLING, ADULT CONTENT, GAMES
During setup, pick the categories you want to block: social media, short videos, streaming, games, shopping, news, gambling and adult content. Add betting sites or adult websites to your blocklist to block them in your browser too. TiedSiren works as a porn blocker, a gambling blocker and a game blocker.

🎓 FOR STUDENTS
Block TikTok and Instagram while you study, and block websites like YouTube and Reddit in your browser. Stay focused during exam season and stop losing your nights to doomscrolling.

💼 FOR WORK AND PRODUCTIVITY
Working from home? Block social media during work hours and get deep focus back. Fewer distractions, more done, better productivity.

🌙 FOR BETTER SLEEP AND LESS SCREEN TIME
Block YouTube and social media at night. Put your phone down at bedtime, cut screen time and break the late-night scrolling habit.

🧠 LESS BRAINROT, NO GUILT
No streaks, no badges, no shame. TiedSiren is a doomscrolling blocker that reduces screen time by removing the choice in the moment. A digital detox that fits your day, not a lecture.

✅ WHY IT WORKS WHEN OTHER BLOCKERS DON'T
Screen time limits and app timers ask for willpower at the worst moment, when the urge to scroll is strongest. TiedSiren asks once, in advance. Block apps and block websites while you're focused, and let the block do the work when you're not. That is how a focus habit sticks.

WHO USES TIEDSIREN
• Students who open TikTok instead of their notes
• Remote workers who need focus and fewer distractions
• Anyone whose self-control works at 9 a.m. and disappears at 11 p.m.
• Anyone who has tried other app blockers and switched them off

🔐 PRIVACY AND THE ACCESSIBILITY PERMISSION
TiedSiren uses Android's AccessibilityService API only to enforce your blocklist. It detects the app in the foreground and, during an active session only, the web address in your browser's address bar. It never reads your messages, emails, documents, photos or passwords. Everything is processed on your device and is never stored, logged or sent. You turn the permission on yourself after an in-app explanation, and you can turn it off anytime in Android Settings → Accessibility. TiedSiren is not an accessibility tool for people with disabilities.
