Built for doomscrollers. Cut screen time, break the endless-scroll habit, and run a digital detox on your own terms — a distraction blocker for study, work, and winding down.

■ Routines
Decide when, which apps, and how hard. Morning focus, evening wind-down, late night — build the rhythms — and habits — you need, and OpLoop turns them on and off for you.

■ Shorts & Reels only (Pro)
Block just the short-form feed — YouTube Shorts, Instagram Reels — and keep the rest of the app. Experimental: Snapchat Spotlight too.

■ Block screen
Every block shows a different card: a gentle poke, a calm line, sometimes a joke that goes right up to the line. Written fresh for each language, never machine-translated, with per-card cooldowns so the same line never becomes wallpaper. Some days you slash the screen and cut the loop yourself.

■ Sprint
A focus session that starts right now, no schedule needed.
• Soft — blocks the apps you picked
• Deep — blocks everything except the apps you allow
• Lockdown — holds until the timer runs out

■ Growth
Time earned back, blocks that held, this week against last. Stats build from moments as they happen, so a new phone or a changed app list never wipes them.

■ Passes
A few short passes a day. Use one when you genuinely need the app; when they run out, the block holds.

■ About the Accessibility Service
OpLoop uses Android's AccessibilityService API to make blocking work: it reads which app just came to the foreground to show the block screen, recognizes short-form screens if you block Shorts or Reels, and drags away a floating window a blocked app keeps playing in. It never reads what you type or your personal content, and nothing it reads is stored or sent anywhere.

■ Your data stays on your phone
Which apps you open, for how long, and what got blocked stays on your device only — never uploaded. Even with an account, the server stores just your nickname, email, and badges (milestone records).

■ No account needed
Everything works without signing in. Create an account only if you want your nickname and badges to follow you. ## Rankings - #3,131,418 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_NOTIFICATION_POLICY` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.PACKAGE_USAGE_STATS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.SCHEDULE_EXACT_ALARM` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.studiojson.oploop.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Blokr: App & Shorts Blocker](https://chrome-stats.com/d/company.hashinclude.blokr) — 757 users - [BreakLoop-App Blocking](https://chrome-stats.com/d/com.breakloop.app) — 31 users - [LoopCut: Screen Time & Focus](https://chrome-stats.com/d/io.loopcut) — 81 users - [Loop Breaker: Earn your scroll](https://chrome-stats.com/d/com.replacer.replacer_checker_v1) — 102 users - [Doomless](https://chrome-stats.com/d/com.pjamalama.blocked) — 17 users - [Unloopy](https://chrome-stats.com/d/com.buildmydesign.unloopy) — 39 users - [Scroll Block:Stop Reels/Shorts](https://chrome-stats.com/d/com.antiscroll.blockreelsshorts) — 30 users - [App Blocker: Stay Focused](https://chrome-stats.com/d/com.screentime.focus.blocker.productivity.focusguard) — 534 users - [Block Shorts & Reels: Focus](https://chrome-stats.com/d/com.syddstudio.blockshorts) — 31 users - [ScrollStop: App Blocker](https://chrome-stats.com/d/com.buttonbird.scrollstop) — 48 users - [Digital Detox: Block Scrolling](https://chrome-stats.com/d/com.augustsoftwares.digitaldetox) — 50 users - [Stop Scrolling & App Blocker](https://chrome-stats.com/d/com.thomas.doomblockai) — 14 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.studiojson.oploop)
