# Mos

Mos is a free, open-source macOS menu bar utility that makes mouse wheel scrolling smooth while preserving mouse precision.

## What Mos does

Mos intercepts mouse wheel events and turns raw deltas into smoother, more predictable motion. It supports per-app profiles, independent vertical and horizontal axis settings, scroll direction control, scroll hotkeys, mouse button bindings, and Logitech HID++ button handling.

Mos is designed for macOS 10.13 or later.
