Nudge - ADHD App Blocker

Raedus Labbs

About this app

App blockers ask for Accessibility Service permissions — the most powerful permission on Android. It can see everything on your screen. Most app blockers are closed-source with vague privacy policies. Nudge is different.

Nudge is open source, requests zero internet permissions, and keeps all your data on your device. No analytics. No telemetry. No data leaving your phone. Ever.

Features:
* Delay-to-open — wait through a breathing exercise or countdown before opening distracting apps
* Hard blocking — completely block apps you don't want to access
* Daily time budgets — allow 30 minutes of Instagram per day, then block
* App groups — create a "Social Media" group, configure once, apply to all
* Schedule-based rules — block social media 9-5 on weekdays
* In-app blocking — block Instagram Reels and YouTube Shorts without blocking the whole app
* Grayscale mode — make blocked apps less appealing by forcing grayscale display
* Usage stats — see where your screen time actually goes

The delay/breathing modes are the core idea. They don't lock you out — they insert a moment of intentional friction that breaks the automatic habit loop driving most mindless phone usage.

Zero internet permission is declared in the manifest — verifiable, not a promise.

What’s new

NEW: Auto-close by time, a rule can now send you home after N minutes in an app (works during passive watching), alongside the existing interaction trigger; whichever fires first wins. Cooldowns are now free-form minutes (up to 24h), so "30 minutes on, 15 off" is finally possible. The daily 2-minute pass is now controlled by its own toggle, Strict Mode gates re-enabling it instead of hiding it. Fixes: rule edits no longer wipe web domains; time limits now block during passive use.
