Download Meter

The Mac and PC apps run beside Zoom, Teams, Meet, phone calls, and in-person conversations. When auto-start is on, Meter starts itself as a Zoom, Teams, or Meet call begins and stops when that call ends. You can still turn it on by hand. Share with room copies a link for the chat. There is no Zoom App Marketplace add-in required.

Mac

Meter

Universal disk image for Apple silicon and Intel. Auto-start is on, the official logo is on the bar and in the menu, and Share with room is a button on the bar. Notes still listens only after you turn Notes on and agree. Ad-hoc signed, 1,890,468 bytes.

First launch on a Mac

Open Meter.dmg and drag Meter onto Applications. This build is ad-hoc signed, so macOS blocks a normal double-click the first time. In Applications, right-click Meter and choose Open, then choose Open again in the dialog. After that first launch, open it from the menu bar as usual.

Browser extension

You do not need this for Meter to start. The desktop app starts when Zoom is in a meeting or the microphone is in use, including Meet in a browser. The extension only draws that cost inside the browser tab. A share link does the same thing for people who install nothing.

Chrome and Edge will not let Meter install the extension for you. A managed work browser can, with an ExtensionInstallForcelist policy. On a personal computer you load it once:

Download Meter-Extension.zip and unzip it. You get one folder named Meter-Extension.
Chrome: open chrome://extensions. Edge: open edge://extensions.
Turn on Developer mode.
Choose Load unpacked and select the Meter-Extension folder. It contains a README if you want the same steps on paper.

Download Meter-Extension.zip

Optional add-ons (advanced)

Zoom, Teams, and Meet already work through the desktop app, the extension, and a share link. Store listings are not published. These sideload packages are only for someone testing a panel.

What you need to buy for signed installs

Windows is signed by Kyle Swan. Rebuilding that installer removes the signature, so sign the new file before publishing it. The Mac disk image stays ad-hoc signed until an Apple Developer Program membership is active. Then set APPLE_SIGNING_IDENTITY, APPLE_TEAM_ID, and APPLE_NOTARY_PROFILE on a Mac before running the DMG script. Auto-update stays off until the Mac build is signed too. No signing secrets are stored in the app.
