You open Chrome to check one thing. Two hours later you're deep in YouTube/Twitter/Reddit.

Refocus stops this. Start a work session, and if you drift to a distracting site or app, you get a warning. Ignore it, and a full-screen overlay blocks everything. Enable hard mode, and Chrome closes entirely.

No willpower required. The app enforces it for you.

1. Start a session from the menu bar
2. Work normally
3. Open a distracting site or app → warning overlay appears
4. Close the distraction → overlay disappears
5. Ignore the warning → screen goes red, Chrome closes (hard mode)

• Websites: YouTube, Twitter/X, Reddit, Instagram, Facebook, TikTok, Netflix, Discord, Hacker News
• Browsers: Safari, Firefox, Arc, Edge, Brave, Opera, Vivaldi
• Apps: Steam, Spotify, Discord, Netflix, games, social media apps

./scripts/reinstall_refocus_app.sh
./scripts/install_native_host.sh

Then load the Chrome extension from chrome://extensions → Load unpacked → chrome_extension/

Everything stays on your Mac. No accounts, no cloud, no tracking.
