Descriptions

One line

iKnowMyMac tells you why your Mac is slow, not just what's running.

One paragraph

iKnowMyMac is a native Mac app that tells you why your Mac is slow, not just what's running. It groups the hundreds of processes macOS runs into the apps you know, keeps 30 days of history on your Mac, and answers “Why is my Mac slow?” with ranked causes and the evidence behind each, worked out on the device. It also shows what kept your Mac awake and where the battery went overnight, and gives developers their dev servers, ports, Docker containers and simulators by project. iKnowMyMac runs on Apple silicon Macs with macOS 15 Sequoia or later, has no account, analytics or telemetry, and is a one-time purchase with free updates: $24.99 per Mac, or $4.99 for the first 100 licenses at launch. It is made by iDevelopApps.
