Your Mac's vitals,
in your menu bar.

A precise, native system monitor for macOS. CPU, memory, network, battery, and 30 days of local history — built quietly into a single menu bar app, with not a single byte sent off-device.

Features

Every sensor you need.
Nothing you don't.

Specto reads directly from the system — Mach kernel calls, IOKit, CoreWLAN — sampled as fast as twice a second. No background daemons, no helper processes, no surprises.

Live CPU & memory

CPU load, real memory pressure, physical RAM, and swap — with a Nominal / Warn / Critical state at a glance.

Top Processes, searchable

The heaviest CPU and memory consumers — with PIDs, paths, search, and End Task. Filter live as you type.

KERNEL · 8.1% · 1.1G

Network history

Bandwidth charts at 1H, 24H, 7D, and 30D. Wi-Fi signal in dBm. Public IP on demand — never auto-fetched.

Battery & thermal

Cycle count, design vs current capacity, time-remaining estimate, and thermal pressure when things heat up.

Privacy

It runs on your Mac.
And only your Mac.

Specto exists because the system already knows everything about itself. There's no reason it should phone home to do its job.

Zero network traffic

No telemetry, no analytics, no remote config. Specto requests network entitlements only to fetch your public IP on demand — never to make calls on your behalf.

No accounts. No sync.

There's nothing to sign up for. Open the app and it works. Settings live in UserDefaults, on your machine.

Local history, auto-pruned

Network history lives on your device and prunes after 30 days. Per-app Resource History is opt-in and clearable any time from Settings.

No Wi-Fi name. No location.

Specto reports a generic Wi-Fi status and signal — it does not read your SSID and does not request Location permission.
