Notice what needs attention
Watch for high CPU usage sustained over time. See the usage, observation window, and task runtime before interrupting legitimate work.

Sometimes the work is finished, but a process keeps running. QuietWatch spots sustained CPU usage, helps explain the task, and leaves the next step to you.

Less investigating. More doing.
From “what’s busy?” to “what next?”
Turn a list of processes into useful context and a next step you can check.
Understand where it came from
Use the process name, local path, and launch command to understand its origin. For another perspective, preview a summary and ask your AI service.
Task origin · Local assessment · Optional AICheck, then choose
Check progress before waiting, muting, or requesting an exit. QuietWatch rechecks the target identity before acting and verifies the result afterward.

The important things come first.
From an overview to all processes and past actions. Clear in both light and dark.
Search, filter, and sort readable processes and their resource usage.

At home in your menu bar
No need to keep watching.
Close the main window and QuietWatch keeps observing from the menu bar. Check in when you need to, or pause observation while you focus on something else.
- Observes every 30 seconds by default; adjustable in Settings
- Pause, resume, or take a fresh sample
- Enable notifications and launch at login when you choose
Know where your data goes
Start local. Ask AI when you choose.
Process observation and rules run on your Mac. Local monitoring and actions work without an AI connection.
Read the full privacy noticePreview before sending
Each AI request shows its destination and exact summary before you confirm.
Only the necessary summary
No raw commands, paths, PIDs, usernames, or project source code are sent.
Keep keys and records in place
API keys stay in macOS Keychain. Local event history can be exported or cleared.
Before you download
A few good questions.
Will it stop a process automatically?
No. QuietWatch shows the evidence and lets you choose whether to mute, request an exit, or force quit. Each exit action requires a separate confirmation. Force quitting may lose unsaved work.
Does high CPU mean an app is stuck?
Not necessarily. Builds, renders, and tests can legitimately use a lot of CPU. QuietWatch shows sustained usage, task origin, and observation time so you can check actual progress.
Do I need to connect an AI service?
No. Monitoring, local rules, and process actions work locally. AI is optional and requires your own compatible service, model, and credentials. Provider charges may apply.
Which Macs are supported?
The universal package includes Intel and Apple Silicon binaries and requires macOS 13 or later. The app interface is currently in Chinese.
Why are some processes missing?
QuietWatch only shows processes readable by the current user. macOS limits access to some process information. You do not need to disable system security.
How do I install or update it?
Open the DMG and drag QuietWatch into Applications. It is signed by JINGREN CHEN and notarized by Apple. To update, quit the old version and replace it with the new download. Updates are currently downloaded from this website.

Compare macOS Activity Monitor with QuietWatch fairly: immediate system-resource inspection versus sustained CPU alerts, task context and confirmed manual actions.
