SAM: System Activity Monitor

$2.99

Price checked at source August 29, 2026.

A lightweight menu bar system monitor covering CPU, memory, GPU, disk, network, battery, and Bluetooth — $2.99, from Meerkey Inc.

Our take

Covers more ground than most budget system monitors — CPU, RAM, GPU, disk, fans/temperature, network, battery, and Bluetooth devices — with a choice of menu bar icon styles (numbers or mini-charts). No independent developer website was found: the App Store listing’s own privacy-policy link resolves to an unedited, template GitHub Pages placeholder rather than a real product site, so this is treated as an App Store-only listing until a genuine homepage turns up.

Worth knowing: The App Store listing’s privacy-policy link resolves to a bare, unedited GitHub Pages template rather than a real product site — no independent developer homepage was found for this app.
