Try it on your own Mac.
Every hand is different. Use the whole app with your own mouse for a month, on your own email and photos, before any money changes hands.
You will need
- Any Mac running macOS 14 or later. To check: click the Apple in the top-left corner, then “About This Mac”.
- About three minutes, that covers the download and one permission. The tuning happens by itself while you use the mouse.
- Nothing else, no credit card and no account.
What happens next
The heart of the setup: drag, then one permission.
- Open the downloaded file and drag the app to Applications. If your Mac asks “Are you sure you want to open it?”, click Open. That question is normal for any new app.
- Give the one permission. The app will ask for “Accessibility” access. This is the switch that lets it steady the mouse, your Mac requires it. The app shows you the exact button to press, and it never sees what you type or read.
- Just start using the mouse. There is no calibration step: it learns your hand from ordinary movement and keeps adjusting through the day. You should feel the difference within the first minute.
