Frequently Asked Questions

Is Multimeter a subscription?

No. Multimeter is a one-time purchase on the Mac App Store. There's no subscription, no account and no in-app purchase.

How do I reinstall Multimeter or put it on another Mac?

Open the App Store app, go to your account page to see the apps you've bought, and download Multimeter again. Sign in with the same Apple Account and you won't be charged again.

How do I get updates?

Updates come through the Mac App Store, the same way as your other apps.

How do I get a refund?

Apple handles refunds for Mac App Store purchases. Request one at reportaproblem.apple.com, signed in with the Apple Account you used to buy Multimeter.

What are the system requirements?

Multimeter needs macOS 13 Ventura or later. It works on Intel and Apple silicon Macs.

What can a meter show?

Your Mac's battery, a Bluetooth accessory's battery, power draw, CPU, memory, disk space, thermal pressure, fan speed, network speed, a timer, a countdown to a date, how much of the day, week, month or year has passed, and your own numbers from a link, a web address, a file or a script.

How do I add more meters to my menu bar?

Press Command-N, or open Settings and click Add Meter…, then pick what to measure and pick a face. You can add as many meters as you like.

Does it still show my battery?

Yes. The battery is the first source in the list and the built-in battery faces show charging, time left and time until full. Battery health, cycle count and temperature are available to every face.

How do I show my own numbers?

Add a meter with the Sent Value source and send it numbers with a link like multimeter://set?key=deploys&value=42 from Terminal, Shortcuts, Raycast or any script. You can also read a number from a web address, a file or a shell command. The Creating Meters guide shows every format.

Why can't I find Fan Speed or Script?

Those two need access that the Mac App Store doesn't allow apps to have, so they're only in the direct download version. In the Mac App Store version, have your script send a multimeter:// link or write to a file instead.

Can a meter warn me?

Yes. In Customize, set a warning and a critical level and whether they apply above or below. The meter changes color as it crosses them, and you can ask for a notification when it goes critical.

Can I change the order of my meters?

Yes. In Settings, drag meters in the In Your Menu Bar list. The top meter sits furthest left.

How do I make my own face?

In Settings, click Create Face… (Option-Command-N) to get a folder of starter files you can edit in any code editor. A face you make works with every source. The Creating Meters guide has the details.

Do my settings sync between Macs?

No. Your meters and themes are saved on each Mac.

Why isn't the time remaining showing?

macOS estimates the time remaining from how you're using your Mac. Right after you plug in or unplug, the meter shows dashes until macOS has an estimate. When your Mac is plugged in but not charging, Time Until shows the percentage instead.

How do I import a face someone shared with me?

Double-click the .multimeter file, or click Import… in Settings (Command-O) and choose it. The face joins your Faces library, ready to use on any meter.

Can I use Multimeter on a Mac without a battery?

Yes. Battery faces show your Mac as plugged in, and you can turn off Show charging on this Mac in Settings. Every other source works the same on any Mac.

Troubleshooting

Meter not showing in the menu bar

  • Open Multimeter again from your Applications folder. If it's already running, this opens Settings.
  • Check that at least one meter is in the In Your Menu Bar list in Settings.
  • If your menu bar is full, macOS hides some items. Settings shows a notice when this happens. Remove a meter or another menu bar item to make room.
  • Check that Multimeter is allowed in System Settings › Menu Bar.

Custom meter not loading

  • Make sure manifest.json is valid JSON (no trailing commas, quotes around strings).
  • Check that index.html is in your meter folder.
  • Open Console.app to look for JavaScript errors.
  • Try a built-in meter to make sure Multimeter itself is working.

Your own data isn't updating

  • Check the output is a plain number (42, 42.5 or 42%) or JSON with a "value".
  • For bigger JSON, check the key path, like data.count or items.0.value.
  • Sent values: the key in the link has to match the key in Customize.
  • Web addresses refresh every 30 seconds at the most. Files update when they change.
  • Scripts must print the number within 10 seconds. Run the command in Terminal first to see what it prints.

Privacy

Everything Multimeter measures stays on your Mac. The only network requests it makes are to web addresses you give it yourself. The app has no account and no analytics. Details are in the privacy policy.
