Made for macOS · For hands that shake

Your hand shakes. The cursor doesn't.

Your hand is not the problem. The cursor just needs to listen better. TrueCursor, built for macOS, learns how your hand moves from ordinary use, automatically, then quiets the shake in the arrow while everything you do on purpose goes straight through. Clicks land where you aim.

A real recording. The top line is a shaking hand. The bottom line is the same hand with TrueCursor, the on-purpose move in the middle still goes through.

At a glance

  • Free for 30 days, no card, no account, nothing renews. $39 once if it helps.
  • Works with your own Mac, mouse, or trackpad. One license supports up to 10 devices. 60-day refund.
  • Hold the fn key any time for the plain mouse. Your movement is processed on your Mac and never uploaded.

What kind of problems does it fix?

The small, maddening ones. Links that take three or four tries because the arrow circles them. Clicks that slip and drag a file somewhere unknown. One click that comes out as two, opening things twice. Scrolling that drifts sideways when you meant to go down.

TrueCursor works on each of these separately: the arrow holds steady, clicks stay where you aimed, accidental double-clicks are ignored, and buttons you approach light up with a soft outline, click, and the click lands on that button, even the tiny ones. If pressing the button is itself the hard part, there is an option that clicks for you when you rest on a target.

Is it hard to set up?

No. There are three steps, and the app holds your hand through each one.

  1. Download it and drag it to Applications, the same as any Mac app.
  2. Allow one permission. Your Mac asks before any app may steady the mouse; the app shows you the exact button to press. It never sees what you type or read.
  3. Just use the mouse normally. There is no calibration step: machine learning tunes it to your hand by itself, and you feel the difference within the first minute.
Worth knowing: your hand changes through the day, medicine wears off, hands tire. TrueCursor keeps quietly adjusting within safe limits, so the help fits your morning hand and your evening hand.

What if it gets in the way?

It can’t trap you. Hold the fn key and the mouse is instantly back to normal for as long as you hold it. Hold both ⇧ shift keys for three seconds and the app switches itself off completely. If it ever has a problem, it steps aside on its own. For drawing, photos, or games, it can step aside automatically too.

Will it help you?

Honestly: it depends on the task, not the diagnosis. It usually helps if you can move the arrow roughly toward what you want, but it shakes, overshoots, or clicks the wrong thing on the way, whether that comes from essential tremor, Parkinson’s, MS, medication, or simply age.

It is not the right tool if the arrow cannot be aimed at all, head tracking, eye tracking, or switch control serve better, and we will say so. It does not help with gaming, and it does not treat any condition. The full fit guide is here.

What does it cost?

Everything is free for 30 days, and we never ask for a card, so nothing can be charged by mistake. If it helps, it is $39, one time, and one license supports up to 10 devices. No subscription. After buying you still have 60 days to change your mind: one email, no questions, and we send a reminder before the window closes. The well-known Windows tool costs $43 and has no Mac version.

Buying for a parent? A license makes a practical gift, here is how to set it up for someone else. If price is a barrier, reduced-cost and free licenses are available through a short private form. Our privacy promise is one page, in plain words.

Common questions

Will it make my pointer feel slow or laggy?

No. Movement you mean to make goes through at close to full speed. The tuning adjusts itself to your hand, and holding the fn key shows you the difference instantly.

Why does it need a permission?

Your Mac requires permission before any app is allowed to steady the mouse. It is a one-time step during setup, and the app walks you through it. TrueCursor does not read your screen, record what you click, or see what you type.

Does it work with my mouse software and two screens?

Yes. It works alongside common mouse software and with more than one screen. If something ever conflicts, the app tells you and helps you fix it. See the compatibility page.

Which conditions does it help with?

It is built for hand tremor however it arrives, essential tremor, Parkinson’s, MS, medication side effects, or simply age. The app learns from your movement, not your diagnosis. Results vary from person to person.

What happens when the trial ends?

The assistance pauses and your normal pointer carries on; the app asks whether it helped. There is no card on file, so nothing gets charged. If you want to keep it, it is $39 one time, and you still have a 60-day refund after that.

Nothing to set up. Thirty days to decide. Nothing to undo.
