Decelerator allows you to customize the acceleration setting of your mouse or trackpad. While System Preferences can change the tracking speed, it doesn't actually allow you to modify the factory default acceleration setting. There are a number of reasons you might want to do this:
1. Gamers often disable mouse acceleration entirely to gain a competitive edge in "twitch" reflexes. With mouse acceleration off, a distance on-screen corresponds with an exact distance your hand must move, and is unaffected by the speed with which it moves there.
2. Windows users often find Mac OS X's relatively high mouse acceleration disorienting and frustrating. Lowering the mouse acceleration can go a long way to easing the transition to a new operating system.
3. Some people prefer higher or lower acceleration settings for many reasons both logical and illogical. If you're one of those people, then Decelerator allows you to tweak to your heart's content.
Decelerator costs $1 (and no, I don't believe in reminding you how that compares to a cup of coffee, though I guess I just did!), with 70 cents of each purchase going to the "feed a starving developer" fund. I've been using the app very happily for the last few months, and I hope it's as useful (in fully unproductive ways!) for you as it has been for me. If you have any comments or suggestions, I'd love to hear them on the forums at http://www.bulldozersoftware.com/decelerator.
One more thing. I hate it when developers charge upgrade fees to users, so new Decelerator versions will ALWAYS be free for existing users.
Ok, two more things. If you have a problem, please please please contact me instead of (or at least in addition to) submitting a bad review. Developers have no way of contacting reviewers for details, and since I am unfortunately confined to only 5 senses, I can't actually fix "Horrible aplication I ever bought". I tried to address the 3 negative reviews so far here: http://www.bulldozersoftware.com/x/blog/2011-07-18-decelerator-gets-3-bad-reviews
* First public release!
A must for a 4K screen
While everyone needs this for deceleration, I’ve used it for *acceleration*.
My 4K Samsung screen has a perceivable lag on mouse pointer rendering because it goes through a secondary peripheral attachment box. But the real problem is moving a mouse across a massive number of pixels and still retaining control to click small things.
With default Apple trackpad settings, a slow tracking pace will have you scratching at the trackpad just to get across from one border to the next. A fast tracking speed will have you feeling like you’re playing a video game when you try to click a small button.
The solution is to set the tracking speed slower so you have control but crank up the acceleration so you can move across the massive pixel distances without lifting your hand. In my specific case, it even counteracts some of the lag as you can get used to using acceleration to compensate.
Cracking app. Great price.
Works so far on Lion
Glad that it can be installed on a per-user basis, and glad that it's integrated with App Store
I wonder though, can you make it so that I can choose notches between 1.5 and 2.0? There could easily be made a way for me to set it to 1.7; please turn off snapping! :)
After trying every other option, I spent a whole 69 pence on one of the most worthwhile bits of software I've ever bought! The biggest problem is I'm reluctant to upgrade (is that the right word?) from snow leopard to mountain lion just in case it doesn't work. I can live without Aperture, Photoshop and Logic for a little while, but if this app stopped working it would be an immediate snow leopard reinstallation!
Currently being used with a steelseries Xai gaming mouse but it worked fine with the magic mouse too.
