Diffee VS iKnowMyMac

iKnowMyMac's answer:

Swift and SwiftUI, with AppKit where needed. It is a native Mac app, not Electron.

iKnowMyMac's answer:

Choose it if you want an explanation instead of a dashboard. It groups about 1,000 processes into the apps you know, and covers slowdowns, disk space, battery drain overnight and app updates in one app. It is a one-time purchase with no subscription and no account. If you want every raw process and column, Activity Monitor is the better tool, and it is free.

iKnowMyMac's answer:

Other system monitors show numbers and leave you to work out the answer. iKnowMyMac gives the answer: it reads the last hour and says which app is slowing your Mac down, with the evidence and one action to take.

iKnowMyMac's answer:

People with an Apple silicon Mac who want to know why it is slow, full or draining its battery, without learning what every process does. It also suits developers who run dev servers, simulators, Docker or local AI models and want to see what those cost.

iKnowMyMac's answer:

Activity Monitor showed me hundreds of processes and no answer. So I built iKnowMyMac: it puts those processes under the apps you know and tells you, in one line, what is slowing your Mac down. It launched on 1 October 2026 and is made by one developer.
