A native system monitor for macOS and iOS. CPU, memory, disk, network and energy at a glance — plus a full, searchable process list on the Mac with one-click quit.
Total load and a per-core breakdown with a live history graph and the top consumers.
Used, wired, compressed and cached, swap and memory pressure — matched to Activity Monitor.
Read/write throughput and IOPS, free space per volume, and per-interface network rates.
Energy-impact index, battery history for the session, power source and thermal state.
Every process with CPU, memory, owner and threads. Search, sort, and quit or force-quit.
Live CPU, memory and network right in the macOS menu bar, without opening the window.
Distributed outside the Mac App Store (Developer ID + notarization) so it can read every process.
iOS sandboxes apps, so a per-process list isn't possible — SysDeck shows the system-wide figures the OS exposes.
iOS sandboxes every app, so none can list or quit other processes. On iOS SysDeck shows the system-wide figures the OS exposes; the full process list is a macOS feature.
Some processes belong to other users or the system and need elevated privileges. Install the privileged helper (macOS) to read and manage all processes, or SysDeck will always let you quit ones you own.
No. Metrics are read locally and never leave your device. There are no accounts and no analytics; purchases are handled by Apple.
