SmartQuit for macOS

The Problem: On macOS, clicking the red ❌ button to close an app window doesn't actually quit the app — it just hides it. Apps keep running in the background, eating memory and cluttering your dock.

The Solution: SmartQuit gives you complete control over when and how apps quit.

Set apps to quit automatically when you close their last window. Add inactivity timeouts. Or keep certain apps running forever. Your Mac, your rules.

Key Features

Automatic App Quitting

Enable the "Quit when last window closes" behavior — per app.

When you close the last window with the red button, the app actually quits instead of staying open in the background.

No more CMD+Q spam. No more apps running silently in the background.

Inactivity Timeout Control

Auto-quit inactive apps after a set number of minutes.

• Set a global timeout (e.g. 30min)
• Override per-app (e.g. don’t quit Zoom, but quit Notes after 5min)
• Disable for specific apps (set timeout = 0)

Quick Quit Panel

View all currently running apps, with:

• Inactivity timer
• CPU & RAM usage
• Multi-select to quit several apps instantly

Why SmartQuit?

• Take full control over how each app behaves — quit on close, inactivity rules, or never quit at all
• Eliminate distractions and memory leaks
• Keep your workspace clean and intentional
• Save time with smarter app lifecycle control

Frequently Asked Questions

Q: Does this work with all apps? A: SmartQuit works with most regular apps (Chrome, Safari, Notes, etc.). System apps like Finder and Dock are automatically excluded for stability.

Q: Will this break my workflow? A: No! You have complete control - enable per-app, set custom timeouts, or disable entirely for apps you want to keep running (like music players or chat apps).

Q: Does it require special permissions? A: Yes, SmartQuit needs Accessibility permission to monitor app windows. This is standard for apps that manage other apps, and you can revoke it anytime.

Q: Is SmartQuit safe to use? A: Absolutely. SmartQuit is code-signed and notarized by Apple, which means it has passed Apple's security checks. The app is also open about what permissions it needs and why.

No subscriptions. Just a focused utility that makes macOS feel more under your control.

Compatible with macOS 11+ (Big Sur and later)
