Questions people ask before they buy

Is there a trial?: The interactive app at the top of the home page uses simulated data, but it's the real layout and the real words. After that, the 30-day refund is your trial.
Why is it on sale?: It's new. The first 25 people take a chance on it, and they pay less for that.
What doesn't it do?: It doesn't control your fans, and it isn't translated yet. There are no Shortcuts actions, AI plan limits or share images.
Is it on the Mac App Store?: No, and it won't be. It reads system interfaces the App Store doesn't allow. It's signed with a Developer ID and sold directly.

Macometer is new, so here's where testing stands.

Installed and run on an M4 Pro Mac mini on macOS 27. Tests and the self test also pass on an M1 Pro MacBook Pro.
CPU, disk, network and memory readings, against top, iostat, netstat and vm_stat.
Clicking the main window's tabs by hand.

A real battery, so MacBook readings have only run against test data.
macOS versions before 27, and Intel Macs.
Clicking the time range, ⌘K and Settings by hand in the installed app. They pass an automated test, which isn't the same thing.
Sleep and wake, per-app volume on real audio, the optional helper, Docker, notifications and a real MCP client.

If it misbehaves on your Mac, the 30-day refund covers it. Please tell us too.
