Cards you can move
Reorder Processor, Network, Storage, Battery, Resources, and Summary by dragging. Collapse, hide, or switch half and full width. Add System, Alert History, Top Apps Today, or Network Quality when you want them.
A local-only monitor for CPU, memory, disk, network, battery, and GPU — with a dashboard you can rearrange, pin, and keep on your desktop.
Features
Live readings in the menu bar, a card dashboard you can shape, and tools that stay out of the way until you need them.
Reorder Processor, Network, Storage, Battery, Resources, and Summary by dragging. Collapse, hide, or switch half and full width. Add System, Alert History, Top Apps Today, or Network Quality when you want them.
Detach the dashboard into a floating window that stays across Spaces. Use ⌥⌘S or the menu bar to focus or close it. ⌘1 / ⌘2 switch tabs; Esc closes.
All-in-one compact bar or separate sensors. Optional sparklines, custom SF Symbols, and smart hide.
Threshold colours, notifications, and battery guards — with density modes from Compact to Detailed.
Adaptive sampling pauses GPU, process, and volume work when nothing on screen needs them.
Customize
Settings split into Menu Bar, Dashboard, History, and Health — so chrome, layout, and alerts stay where they belong.
Translucent chrome that follows system light and dark.
Solid deep-dark panels for high-contrast environments.
Privacy
No accounts. No analytics. No selling data. Optional history is off by default and stored only on this Mac.
CPU, memory, volumes, speeds, battery, and processes are read on device for display — not uploaded as telemetry.
Network and per-app Resource History live under Application Support, auto-prune after 30 days, and clear when you turn them off.
SSID may appear in Network and widgets for display. It is not written to history files and is not sent to a server.
No accounts or in-app analytics. Optional taps: Public IP via ipapi.co, or Network Quality probes to Cloudflare. Developer ID builds also check specto.biz/appcast.xml for updates (Sparkle).
What can leave your Mac: Public IP refresh (ipapi.co) and Network Quality (five HTTPS probes to Cloudflare) run only when you start them. Signed builds may fetch the Sparkle appcast for updates. Results are not stored as telemetry. Full detail matches the repo’s privacy policy for Specto 1.6.0.

Testimonials
Here is what Mac users say about Specto’s lightweight, local-only performance.
“Specto replaced three status bar utilities for me. The auto-fit dashboard and instant zero-CPU background mode make it indispensable on my Mac Studio.”
“Finally a Mac system monitor that respects privacy! No analytics, local history logging, and customizable cards. Exactly what a system utility should be.”
“The Desktop Widgets and live thermal maps are gorgeous. It feels like a native Apple app built with pure SwiftUI precision.”
