What is Tether?

Editorial review
Tether is a Mac app that places a physics-driven ball on an elastic rope hanging from your menu bar. It's designed to give your hands something to do during long meetings, preventing you from reaching for your phone and losing focus. The ball interacts with your actual desktop windows as surfaces, rolling along edges, bouncing off windows, and dropping off ledges. You can drag, throw, cut the rope to let it roam freely, or use magnet mode to chase your cursor. With seven unique ball personalities, adjustable physics (gravity, bounce, size, rope tension), and support for multiple balls that collide with each other, Tether provides a silent, non-intrusive fidget experience. It never steals focus, clicks pass through except on the ball and rope, and a single shortcut (⌥F) hides it instantly. No account, telemetry, or cloud sync, your bounce count stays local on your Mac. It's a one-time purchase on the Mac App Store, requiring a recent version of macOS.

The ball rolls along desktop windows, bounces off them, and can be dragged, thrown, or cut loose.

How does Tether compare to Mac Pet as a desktop fidget?

It also emphasizes privacy with no account, telemetry, or cloud sync.
