For a hand that shakes

Can an essential tremor computer mouse feel steadier?

Yes, for many everyday Mac tasks. TrueCursor calms the arrow while your on-purpose movement goes through. It works with the mouse, trackpad, or trackball you already use.

Essential tremor is usually a faster, smoother wave than Parkinson’s. This recording uses that shape. The top line is the hand; the bottom line is the arrow your eyes follow.

Start with the hard moments

What can you try with a steadier pointer?

Small targets

Open one small link

See if the arrow settles sooner. Count how many tries the click takes.

Careful clicks

Choose one photo

See if one click stays one click. A small hand slip should not drag the photo.

Long moves

Cross the screen

Make sure the arrow still follows when you mean to move a longer way.

A common comparison

Is TrueCursor the same as SteadyMouse?

No. SteadyMouse is a separate product made for Windows. TrueCursor is made for Mac. Both are meant to make an ordinary pointer steadier. TrueCursor also works with Mac trackpads and helps prevent slips during a click. TrueCursor is not affiliated with SteadyMouse.

Your own result matters

How will you know if it helps?

Compare the same task with TrueCursor off and on. Look for fewer missed clicks and less effort. Results vary from one hand and task to another.

You stay in charge

What if it does not feel right?

Adapts

It keeps up with change

It learns your movement automatically, with nothing to run, and keeps adjusting as your tremor changes through the day.

Pause

Stop it instantly

Hold fn for your normal pointer. You can also pause or quit from the menu bar.

Private

Keep movement on your Mac

Your movement is handled on your Mac and then discarded. Nothing about your hand is sent to us.

TrueCursor helps with computer tasks. It does not diagnose or treat essential tremor.
