Everything you need to know about your Mac, nothing you don’t.
CPU & Per-Core Monitoring
Total CPU usage at a glance plus a per-core bar graph breakdown in the detail popover. See exactly which cores are working hard.
Memory & Disk Usage
Used vs. total RAM with progress bars and sparkline history. Disk capacity shown the same way—know when you’re running low before it’s a problem.
Network Throughput
Upload and download bytes per second with separate sparkline graphs for each direction. Spot unexpected traffic or verify your downloads at a glance.
Temperature Alerts
CPU and GPU temperatures via SMC with color-coded warnings—green under 75°C, yellow at 75°C, red at 90°C. Know when your Mac is running hot.
Fan Speed Control
Monitor fan RPM in real time, or take manual control with the optional privileged helper. Set custom fan speeds when you need maximum cooling.
8 Theme Presets
Colorful, Mono, Pastel, Neon, Ocean, Midnight—pick a preset or customize every sensor color individually. Adapts to dark and light mode.
Designed to look as good as the data it shows.
Your menu bar, your way.

Update intervals from 1 to 10 seconds. Graph widths from 20 to 80 pixels. Heights from 12 to 24 pixels. It’s your menu bar.
Graph Only Mode
Compact sparklines with no text—maximum data, minimum space
