SignalRoom for macOS
Know what your Mac is doing.
Live readings. Clear graphs. Right in your menu bar.
Your menu bar
Build your own menu bar.
Open Settings and drag the readings you want into a picture of your menu bar, along it to reorder, or off it to remove. Your real menu bar changes as you go.
Click any item to show a graph, rounded bars or just the number, then set the spacing between items and how the date and time read.
Core monitoring
Start with the essentials.
CPU and per-core activity, memory pressure and swap, network speeds, disk space and activity, battery charge with time left and watts, and a clock with your own world cities and upcoming calendar events.

Illustrative readings. Calendar access is optional and needs your permission.
Usage history
Look beyond the moment.
Explore recorded history. Drag across the chart to select an interval and line up what every other reading was doing at the same time, then export the detail as CSV or PNG.
AI usage
A clearer view of your AI usage.
See Codex limits and local Claude Code usage a click away, with model and project breakdowns. Costs are estimates from local records and known model prices, not subscription charges or account-wide bills.

SignalRoom is free to download with no subscription. The planned Australian price for Pro is A$6.99, once; your local price shows before you buy.
Quiet by default
Notifications start off. Choose the categories, thresholds, sustained durations, repeat cooldown and quiet hours that suit you.
Local by design
Monitoring and AI usage data are processed on your Mac, not uploaded. You choose which AI folders SignalRoom reads and where exports go. Missing readings stay unavailable instead of showing as zero.
SignalRoom Helper
App Store apps can't read temperatures, fans or GPU counters from inside the sandbox. The free, optional helper supplies them. SignalRoom works without it.
