A system monitor in your menu bar, arranged your way.
CPU, memory, GPU, Neural Engine, network, disk, temperature, fan speed, battery and what is left of your AI plans, each its own menu bar item, as a number, a graph or both, in your order and your colours. A reading turns red while something is wrong, so you only look when it matters.

One item per reading, in the order you think of them.

You only look when something is wrong.
A reading turns red while it is under strain and goes back to normal when it passes, so you can forget the bar is there until it changes colour. Click it and the dropdown tells you which limit was crossed and for how long.
- CPU or GPU at 90%, memory under pressure, a nearly full disk, a hot Mac
- Back to normal on its own when it passes
- The dropdown says which reading, which limit, how long
- The battery turns red at 20% on its own
Every reading, and the apps behind it, one click away.
Click any item and the dropdown opens on the Overview, as tiles or as a list with one line per reading, with the busiest apps right there and a tab for everything else, so most questions never need the window.

Menu bar monitor, before and after
Activity Monitor has no place in the menu bar beyond its Dock icon, which can show a CPU graph. Everything else means opening the window. The menu bar monitors that fill the gap tend to go one of two ways: a strip of every reading at once, or one combined item that opens a wall of charts.
What you want up there is small and yours: the two or three readings you glance at, in the order you think of them, and a way to tell at a glance when one needs you.
In Vitals every readout can be its own menu bar item, a number, a graph or both, with or without its icon, ⌘-dragged into any order like any other menu bar item. A reading turns red while it is under strain and goes back when it passes. Click one and the dropdown shows every reading with the apps behind it; click an app and the window opens on it.
Where it is in Vitals
The tab, the menu bar item and the setting, in the order you would reach for them.
- 01
Choose the readouts
Settings → Layout → Menu Bar: CPU, memory, GPU, Neural Engine, network, disk, temperature, fan speed, battery and your AI plans, each as a number, a graph or both, with or without its icon and caption. There is a compact size for small screens, a frame for the graphs, and a colour for each reading if you want one.
- 02
Put them in your order
⌘-drag the items along the menu bar, as macOS lets you with any item. Readouts that share the Vitals item keep the order you give them in Settings.
- 03
Let red do the watching
Turn on Show Readings in Red Under Strain and a reading turns red while the CPU or GPU is at 90%, memory is under pressure, the disk is nearly full or the Mac is hot. The dropdown then says which reading, the limit it crossed and for how long. The battery turns red at 20% on its own.
- 04
Open the dropdown
Click any item. The Overview comes as tiles or a list with one line per reading, every tab is a click or ⌘1 to ⌘0 away, and Esc closes it. Hover over an app for its close button, click an app for the window, or right-click the item for Settings and Quit.
Menu bar monitor: Activity Monitor and Vitals
The whole comparison is row by row. These are the rows about menu bar monitor.
Activity Monitor 
Vitals The words behind it
What the numbers mean, from the Activity Monitor glossary.
- Menu bar item
A menu bar item is an icon or figure at the right end of the Mac's menu bar, put there by an app or by macOS, with a menu or a panel behind it.
- Memory pressure
Memory pressure is Activity Monitor's graph of how well the Mac's RAM is meeting current demand.
- % CPU
% CPU is the share of processor capacity a process is using, measured per CPU core.
- Mbps and MB/s
Mbps is megabits per second and MB/s is megabytes per second.
- Thermal throttling
Thermal throttling is when a computer lowers its processor speed to keep temperatures in a safe range.
Questions
The ones people ask about menu bar monitor before they buy.
Can I arrange the menu bar like iStat Menus?
Yes. Every readout can be its own menu bar item, a number, a graph or both, and you ⌘-drag them into any order. The dropdown and the window are yours to arrange too.
Which readouts can go in the menu bar?
CPU, memory, GPU, Neural Engine, network, disk, temperature, fan speed, battery and what is left of your AI plans. The temperature item can follow the CPU, the GPU or the hottest sensor.
Does it live in the Dock or the menu bar?
Both, if you like. It is always in the menu bar. Turn on Show in Dock and it stays in the Dock like Activity Monitor; opened by hand it shows its window, and at login it stays in the menu bar.
Can I close the window and keep the menu bar?
Yes. Close the window and Vitals keeps watching from the menu bar, taking a reading every five seconds and using about a tenth of a percent of one core.
Can it show memory pressure instead of memory used?
Yes. The memory readout can show memory pressure, memory used or free memory, whichever you watch.
Does the network readout show upload and download?
Yes, upload beside download, and you can turn upload off in Settings → Layout → Menu Bar. Speeds come in bytes or bits, your choice in Settings → General → Units.
Is there a size for a small screen?
Yes, a compact size for the menu bar items, in Settings → Layout → Menu Bar.
Can I use the dropdown from the keyboard?
Yes. Tab moves through its tabs, ⌘1 to ⌘0 jump to one, and Esc closes it. A shortcut from Settings → General opens it from any app.
