ActiveStat
System awareness, simplified.
Stop guessing why your Mac is warm. ActiveStat provides real-time insights into CPU, Memory, Disk, and Battery Impact — without the anxiety of constant notifications. Quiet when your system is efficient. calm when you need to act.
CPU insight
Understand your processing power. Monitor total CPU usage, differentiate between Performance vs Efficiency core activity, and view a visual history graph with real-time load classification.
Memory usage
See how apps affect your system performance. ActiveStat separates App Memory from Wired and Compressed system memory — finally, the math adds up.
Battery health
Monitor capacity, cycles, and real-time temperature. Know your Energy Impact before your battery runs out, not after.
Storage status
Monitor disk usage and system impact. Clear warnings when macOS may limit background tasks — before it affects your workflow.
Your Mac. Your rules.
Toggle status cues, app lists, and default views. ActiveStat adapts to how you work — not the other way around.
Core Features
CPU Profiling
Differentiate between Performance and Efficiency core activity in real-time to understand exactly how your Apple Silicon Mac distributes its workload.
Battery Impact
A real-time Energy Impact score based on CPU load and thermals. Know instantly if your workflow is "Calm" or "High Drain" before your battery runs out.
Memory Mystery Solved
Breaks down usage — App Memory, Wired, and Compressed shown separately. The numbers that always confused you finally make sense.
Sustained Load Engine
Filters out transient spikes — opening a tab, saving a file. The Smart State Engine only notifies you when load is genuinely sustained.
Built for Apple Silicon
Understands the difference between Performance Cores and Efficiency Cores. Context, not just raw data — designed specifically for M-series Macs.
