SteerMouse remaps mouse buttons, tunes scrolling and sets cursor speed per app on a Mac. But it doesn't work with Apple's Magic Mouse or Trackpad, major upgrades are paid, and version 4 settings don't carry over to 5. - **Value for money: A.** $19.99 one-time for version 5, a lifetime licence for that version, under a year of this category's typical subscription. - **Free plan and trial: C.** A 30-day free trial, with no card mentioned. No free edition after it. - **Features: C.** Button assignments, per-app settings, cursor speed, scroll tuning and snapping. It does not support the Magic Mouse or Trackpad, which the listing names as a gap. - **Ease of use: C.** Many settings to work through per mouse and per app. No store rating is on record. - **Platforms and integrations: C.** Mac only, macOS 12 or later for version 5.8.2. No other platform. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Plentycom Systems's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. ## Where it stands among desktop utilities - SteerMouse's GPA of 2.4 is higher than 35 of the 186 other desktop utilities we grade, and level with 33. - It stands best on value for money (A, above 55 of 186) and worst on features (C, above 2). The category's chart of price against score: https://toolgpa.com/charts/utilities ## Keep it, or make your own? **Keep it.** To replace SteerMouse you would be making keys and buttons remapped below the level of apps. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 118 of the 186 other desktop utilities grade higher. It costs $19.99, paid once. - You could not: Keys and buttons remapped below the level of apps. - You could not: A real app for macOS. Something home-made would be a web page.
