Your Mac's health,
at a glance

Is your Mac OK, and is there anything you should do? Pollymetric answers from your menu bar, names what's slowing it down, and lets your AI agent explain and fix it.

See it work

From a glance at the menu bar to a fix, without leaving the process you're looking at.

Three simple steps
to get started

No account and nothing to configure. A short setup gets it running the way you want.

1

Download and drag to Applications

Get Pollymetric.dmg, open it, and drag Pollymetric into Applications.

The setup window The setup window in dark mode
2

Open it and follow the setup

Start at login, the one permission that lets it check your whole Mac, the cleanup and security tools (installed for you), and any AI agents it found. All optional.

Get on with your day

It lives in your menu bar, gray while all is well, and speaks up only when something needs you.

First open: this early build isn't notarized by Apple yet, so macOS will say it can't verify the developer. Open System Settings → Privacy & Security and click Open Anyway. Notarized builds that skip this step are coming.

Built to stay out
of your way

A monitor shouldn't be the thing slowing your Mac down, and what it records about your Mac is yours. So it's light, local and asks before it acts.

~0.4%

CPU while it watches from your menu bar, so the monitor never becomes the problem.

Two weeks of history

The spike that lasted twenty seconds is still on the record.

Private by design

Everything stays on your Mac. No account, no cloud, no tracking, and this site doesn't track you either.

Let your agents check in, on your terms

Connect Claude Code or Codex so they can ask how your Mac is doing. You approve each one with Touch ID, see what it looked at, and can revoke it any time. Anything that would change your Mac asks you first, every time.

The kind of thing
it catches

Everyday ways a Mac gets slow, and what Pollymetric shows you instead of "node".

A build watcher stuck in a loop

It rebuilds whenever its own output changes. Flagged after it flared up seven times in a day, with the fix from your agent.
