BrainShield: Block Reels

Your attention is the product. Reels, Shorts and infinite feeds are built by large teams to hold it as long as possible. BrainShield closes those screens — and only those screens.

Open Instagram and it works normally. Swipe to Reels and BrainShield closes that one screen. You keep the app. You lose the trap.

■ WHAT IT BLOCKS • Short-form feeds — Instagram and Facebook Reels, YouTube Shorts, TikTok, X's video tab, YouTube Music Samples • Reddit NSFW content • Adult sites in any app or browser, via an on-device DNS filter • Any app you choose — games, social, shopping, news

■ HEAVY FOCUS MODE For the day willpower runs out. Distraction rewires you to want more of it, so the moment you feel like switching protection off is the moment it matters most.

Heavy Focus Mode locks every switch. Turning it off means retyping a freshly generated 16-character code, shown only at that moment. Optional uninstall protection stops the app being removed until you disable it from inside. Streaks track every day you hold the line, with milestones at day 2, day 4, then weekly and monthly.

■ TWO BLOCKING ENGINES

Screen detection — reads the foreground screen and closes blocked surfaces in real time, including modded clients that rename themselves to dodge simple app blockers.
Local DNS filter — resolves blocked domains to nothing, covering every app, browser and in-app web view, not just the ones on a list.
■ BUILD THE HABITS TOO • Pomodoro timer — focus rounds, a task list with per-task estimates, focus sounds, 7-day history, and it keeps running with the screen off • Water reminder — daily target, glass size, active hours, one-tap logging • Step counter — daily goal, distance and calories, with bike and car rides filtered out so they never count as steps • Alarms — task alarms with schedules and spoken reminders • Minimal launcher — an optional home screen with no icon grid to fall into • Time Saved — see what blocking actually gave back to you • Calendar — every habit, day by day • Home-screen widgets for water, Pomodoro, steps and alarms • Notification control — decide exactly what is allowed to interrupt you

■ WHY IT WORKS WHEN OTHER BLOCKERS DON'T Most app blockers only know app names, so a modded client that renames itself walks straight past them. BrainShield checks four layers before it acts — your own locked list, the package name, the exact screen you are on, and the shape of the feed itself — so a renamed clone still gets closed.

■ COMMON QUESTIONS Does it block the whole app? No. It closes only the screen you chose. Instagram messages and posts keep working while Reels does not. Can I get out if I really need to? Yes. Ordinary switches turn off any time. Only Heavy Focus Mode makes you type the code first. Does it work in Chrome and other browsers? Yes. The DNS filter covers every app, every browser and in-app web views. Does it need root? No. Will it keep working after a restart? Yes, everything comes back automatically.

■ BUILT TO SURVIVE REAL PHONES Services restart after a reboot. A health check detects the force-stop "zombie" state — where Android still lists a service as enabled but never re-binds it — and tells you how to repair it, instead of silently protecting nothing.

■ HOW IT USES ACCESSIBILITY BrainShield uses Android's Accessibility Service to detect and close specific screens (Reels, Shorts, Reddit) inside the apps you choose to restrict, and to close any app you lock in Heavy Focus Mode. It does not read or store your personal content.

The VPN permission runs a local DNS sinkhole on your own device. Your traffic is not proxied through any server of ours.

■ GOOD FOR Digital detox, screen time control, beating doomscrolling and procrastination, study focus and exam prep, deep work, self control, phone addiction recovery, and staying off short-form video.
