Tether

What is Tether?

A ball hangs from your Mac menu bar on an elastic tether. Drag it, fling it, slingshot it. It bounces off your actual app windows, rolls along their edges and settles into the Dock. Cut the rope and it goes loose across the desktop. Real physics, not a canned animation, so it never does the same thing twice. One key hides it the instant somebody says your name. No account, no subscription, nothing leaves your Mac.
