# Everything about one app, in one drawer.

Activity Monitor shows processes one row at a time, and only while they run. Tidix opens a drawer for the whole app: its processes added up, its history, its size and its [related files](https://tidix.app/glossary#related-files), with Uninstall at the bottom.

## Click an app wherever Tidix lists it

The drawer opens from the Apps list, from Summary's Top apps, from the app lists on Performance, and from any process inside an app on the Processes page. It slides in over the page, which keeps updating underneath, and its header shows the app's version, whether it is running, its [uptime](https://tidix.app/glossary#app-uptime) and when you last used it.

- **Apps**: click a row, or move through the list with the arrow keys and the drawer follows.
- **Processes**: choose Show App Details in the inspector or in the row's menu.
- **Search**: press ⌘K, type the app's name and pick it.
- Click another app and the drawer switches in place; Esc or a click outside closes it.

## Every process the app runs, added up

The Processes tab counts every process inside the app's bundle as part of the app, [helper processes](https://tidix.app/glossary#helper-process) included. Cards add up their memory, CPU, power draw, disk reads and writes and network traffic next to the app's size on disk, and the list shows each process with its PID, CPU and memory, busiest first.

- Sort the list by name, PID, CPU or memory with a click on the column.
- **Quit** and **Force Quit** act on the whole app, and both ask first.
- **Show in Finder** reveals the app's bundle.

## One app over the last 5 minutes or 30 days

The Performance tab charts this app alone: memory, CPU, power draw, network and disk. **5 minutes** is live, kept in memory since Tidix started; **1 hour** and **24 hours** show hourly averages and **7 days** and **30 days** daily averages from the saved metrics history, counted only while the app ran.

- The line breaks over the hours or days the app was not running, instead of drawing a zero.
- The history is recorded while **Save metrics history** is on in Settings, which is the default.

## What the app is and where it keeps its files

The Info tab reads the app's bundle: its [bundle identifier](https://tidix.app/glossary#bundle-identifier), version, source, when it was last opened and modified, its path and whether it runs at startup. Two tiles total its size and its related files, and the list under them names each file in `~/Library` with its size.

- **Source** says Apple, App Store, or the developer who signed the app.
- **Runs at startup** counts the startup items the app owns, and Show opens them in the Apps page's Startup view.

## Uninstall moves the app and its leftovers to the Trash

**Uninstall…** asks first, and says how many related files go with the app and how much space they take. Everything goes to the Trash instead of being deleted, so you can restore it from there, and the drawer closes once the app is in the Trash.

- Tick **App only, without related files** to keep them.
- It looks in Application Support, Caches, Preferences, Containers, Logs, Saved Application State, HTTPStorages, WebKit and Cookies, by the app's name or bundle identifier.
- Apple's own apps are part of macOS, so Tidix never offers to uninstall them.

## Before and after

### With Activity Monitor

In Activity Monitor you hunt for the app's processes row by row, add up its helpers yourself and see only what they use right now. To remove the app you drag it to the Trash in Finder, and its folders in `~/Library` stay behind.

### With Tidix

In Tidix you click the app. The drawer adds up every process, charts up to 30 days, lists its related files with their sizes, and **Uninstall…** moves the app and those files to the Trash after asking first.

## Where it is in Tidix

1. Open **Apps** in the sidebar (⌘4) and click an app, or click one in Summary's Top apps or in an app list on Performance.
2. On **Processes** (⌘3), select a process that belongs to an app and choose Show App Details.
3. Switch between the **Processes**, **Performance** and **Info** tabs, and press Esc to close the drawer.

## App details: Activity Monitor and Tidix

| What | Activity Monitor | Tidix |
| --- | --- | --- |
| What a row is | One process; an app's helpers are separate rows | The whole app, with every process inside its bundle added up |
| Closed apps | Running processes only, or the apps of the last 12 hours | Any installed app, with a Not running tag and when you last used it |
| History | Live values; no charts of one app over hours or days | Charts of one app over 5 minutes, 1 hour, 24 hours, 7 days or 30 days |
| One process up close | The Inspect window shows its stats, open files and ports | The Processes tab lists each process with its PID, CPU and memory |
| Size on disk | Not shown | The app's size, plus each related file in ~/Library with its size |
| Uninstall | Not offered; dragging an app to the Trash in Finder leaves its files behind | Moves the app and its related files to the Trash after asking first |

## The words behind it

- [Related files](https://tidix.app/glossary#related-files): Files an app keeps outside its own bundle, mostly in `~/Library`: support folders, caches, preferences, containers, logs, saved window state and cookies. Dragging the app to the Trash leaves them behind.
- [Helper process](https://tidix.app/glossary#helper-process): A separate process an app starts from inside its own bundle to do part of its work, such as rendering web pages. Activity Monitor lists each one on its own row; Tidix adds them up under their app.
- [App uptime](https://tidix.app/glossary#app-uptime): How long an app has been running. Tidix counts it from the start of the app's oldest process still running, helpers included.
- [Bundle identifier](https://tidix.app/glossary#bundle-identifier): The unique reverse-DNS name a Mac app declares in its Info.plist, such as `com.apple.Safari`. Most of the app's preferences, containers and caches are named after it.

## Questions

### What does Uninstall remove?

The app itself and, unless you tick **App only, without related files**, the related files the Info tab lists: its folders and files in `~/Library`, such as Application Support, Caches, Containers and Preferences. Nothing else is touched.

### Can I undo an uninstall?

Yes, until you empty the Trash. Tidix moves the app and its files to the Trash instead of deleting them, and the confirmation reminds you that you can restore them from there.

### Why can't I uninstall some apps?

Apple's own apps are part of macOS, so the Uninstall… button stays dimmed for them.

### Why is an app's history empty?

The 1 hour to 30 days ranges read the saved metrics history, which starts when Tidix starts recording and only covers the hours the app ran. If **Save metrics history** is off in Settings, the tab tells you to turn it on; the 5 minutes range works either way.

### Does it show GPU use per app?

No. Tidix measures GPU use for the whole Mac only, so the app's GPU card shows a dash. The GPU itself is on the [Performance](https://tidix.app/features/performance) page.

### Which processes count as part of an app?

Every process whose program sits inside the app's bundle, helpers included. A browser's helper processes add up under the browser, and an app nested inside another app's bundle counts toward the outer one.
