Mos vs Smooze (2026): which should you pick?

Pick Mos if

• Fits if you use a wheel mouse on a Mac and want it to scroll like a trackpad
• Works for per-app scroll settings

Look elsewhere if

• Not for you if you use Windows or Linux, as it is Mac only
• Watch out: the CC BY-NC 4.0 licence is non-commercial, not a standard open source one
• Too light for you if you want paid support: its own comparison page points those users to commercial tools
• Watch out: it needs the macOS Accessibility permission

Pick Smooze if

• Fits if you use a wheel mouse on a Mac and want animated scrolling plus button gestures
• Works for per-app and per-display scroll settings

Look elsewhere if

• Not for you if you use Windows or Linux, as it is Mac only
• Watch out: the vendor's own site gives no price, only the Paddle checkout does
• Watch out: one licence covers two Macs, and moving it to a new machine goes through support
• Tight if you want to decide quickly, since the trial is 7 days

Mos

• Mac only; it needs the macOS Accessibility permission to work.
• Licensed under CC BY-NC 4.0, which is a non-commercial license rather than a standard open source one.
• Its own comparison page says users who want paid support or a commercial product lifecycle may prefer commercial tools.
• Pointer acceleration and broader device settings are better handled by other tools, according to the vendor.

Smooze

• Mac only; the site lists macOS Catalina 10.15 and up.
• The price is shown only in the vendor's Paddle checkout, as US$19.99 before VAT; the vendor's own site gives no price.
• One license can be used on two Macs; moving it to a new machine goes through support.
• People who bought the earlier non-Pro version are pointed to a separate download.

Mos

Smooth wheel scrolling

Turns raw wheel steps into continuous motion, with step, speed and duration values that can be tuned.

Per-app profiles

Each app can inherit the defaults or override its own scroll and button behavior.

Separate axes and reversal

Vertical and horizontal scrolling are configured independently, and direction can be reversed per axis.

Mouse button bindings

Record a mouse, keyboard or custom event and bind it to an action such as Mission Control, Spaces, screenshots or a script.

Logitech button support

Handles button events from Logitech devices connected over Bolt, Unifying or Bluetooth.

Scroll hotkeys

Keys can be bound to accelerate scrolling, convert the axis or temporarily turn smoothing off.

Smooze

Animated scrolling

Adds smooth, animated scrolling to a scroll wheel mouse in every app.

Button actions and gestures

Attach mouse buttons to actions, and assign gestures and rocker gestures to buttons, shortcuts or apps.

Auto scroll

Scrolls anywhere on the screen hands-free with animated movement.

Grab, drag and throw

Grab the screen to scroll; throwing it animates the scroll the way a trackpad does.

Free acceleration control

Turn off scroll acceleration and choose lines per tick. The vendor says these features are and will stay free.

Per-app and per-display settings

All settings can be set for each app on each display.
