Nikad Device Health Monitor

Know what your Mac is doing, at a glance.

About

Nikad Device Health Monitor is a native macOS app that brings together the health signals you'd otherwise have to go hunting for across Activity Monitor, System Settings, and Finder — battery condition and thermal state, memory pressure, storage usage (with a built-in duplicate-file finder), live per-core CPU load, Wi-Fi and network diagnostics, and a one-screen audit of which privacy permissions your other apps have been granted.

Everything is read locally on your Mac. Nothing is uploaded, tracked, or shared — see the Privacy Policy for the full detail.
