A calmer way to use your Mac
One app at a time.
Everything else gets out of the way.
1AppMode automatically hides the app you were using when you switch to another one. No window shuffling. No desktop pile-up. Just the app you chose.
A simple menu-bar utility for macOS.

1AppMode is off. Safari and Notes can both remain on screen.
The idea
Work with one app at a time.
1AppMode makes the rest disappear.
Most window-management tools help you arrange more windows. 1AppMode takes the opposite approach: when you move on, the previous app gets out of sight. The result is a desktop that continually cleans itself up.
Less managing. More doing.
Same Mac. Different rhythm.
Without 1AppMode
Apps accumulate.
Windows stay behind other windows. Switching tasks leaves visual residue everywhere.
With 1AppMode
The desktop resets itself.
Switch apps and the previous one is hidden. Your attention moves without the clutter following you.
How it works
It changes one behavior.
That changes the whole desktop.
Use any app
Work normally in Safari, Mail, Notes, Xcode, Photoshop—or anything else on your Mac.
Switch apps
Use the Dock, Command-Tab, Spotlight, or however you already move between applications.
The old app disappears
The application you left is hidden—not quit—so the newly active app becomes the only one in view.
Made for focus
Useful whenever the background becomes the distraction.
01
Deep work
Keep the task you chose visually dominant without manually hiding everything else.
02
Presentations
Switch applications without leaving unrelated windows hanging around behind them.
03
Small screens
Make a laptop display feel less crowded by eliminating leftover app windows.
04
Desktop minimalists
Get a clean workspace as a behavior, not as a chore you repeatedly perform.
