Cmndr
A system monitor for everyone.
Overview
Your Mac, at a glance.
Whether you just want to keep an eye on CPU usage or you need GPU temperatures, per-core breakdowns, and top processes — Cmndr puts it all in your menu bar where you can see it at a glance. Five live graphs sit in your menu bar, and a single click opens a detailed panel with everything you need to know.
What you can monitor
Five letters. Everything that matters.
Computer
Total CPU and GPU usage, per-core breakdown, renderer and tiler utilization, and the top processes eating your CPU.
Memory
Pressure level, usage by type — app, wired, compressed, cached — and the processes using the most memory.
Network
Download and upload speeds, packet rates, and your IP addresses. Click to copy.
Disk
Read and write throughput, I/O operations, capacity per volume, and swap usage.
Resources
Battery level and health, 24-hour charge history, power draw in watts, CPU and GPU temperatures, and thermal state.
