ActivityMonitor+ is a native Mac menu bar app that tracks RAM, CPU, disk, network, battery, audio, and app focus — all in one place, running quietly in the background.
Ships with a bundled background helper that starts automatically and keeps running even after you close the dashboard.
Eight focused tabs — each telling a clear story about your Mac right now.
See every running process grouped by parent app, sorted by how much RAM it's using. Spot the process quietly eating gigabytes in the background.
The same process tree, sorted by CPU usage instead of memory. Instantly find what's making your fan spin or draining your battery fastest.
A background daemon watches your disk 24/7 and logs write bursts. The Disk tab shows you which directories grew, which files changed, and which apps were actively writing at the time.
See your current network speed at a glance in the menu bar, and drill into the Network tab for a breakdown by process.
Check your battery health, current charge rate, and recent discharge history. Understand whether you're on AC, how fast you're draining, and whether your battery is healthy.
See exactly which apps currently have access to your microphone or audio output. No more wondering if something is listening.
Tracks which app is in the foreground throughout the day. See a timeline of your active windows and understand where your time actually went.
Define per-process memory limits. Get a native notification when a process blows past its threshold — and optionally kill it automatically.
