A macOS focus tool with one mechanic: the apps you want to work in stay vivid. Everything else fades to gray the moment you switch to it.
Nothing is blocked. Nothing is logged. The distractions you used to crave just feel… less alive.
Blockers fight your willpower head-on. They build walls, count streaks, lock you out, and shame you when you slip.
Drain does the opposite. Your distracting apps are still right there — one switch away. You just won't want to be in them as much, because their color, their motion, their dopamine — it all goes flat.
The friction is aesthetic, not punitive. There's nothing to push against.
Drain doesn't have its own grayscale engine. It runs the one already in macOS — which means it works in every app, including full-screen games, video, and screen-sharing.
Drain uses two macOS Shortcuts to flip your Color Filter accessibility setting on and off. That's the whole engine. No kernel extension, no screen overlay.
Add a few apps that should stay in color — your editor, your writing app, your CAD tool. Or invert it: list the apps you want to drain, and leave the rest alive.
When you switch to a focus app, color comes back. Switch away, and the world fades. No notifications. No streaks. No nags. Just the visual nudge, every time.
