Seems to have more options than most...released June 6th, 2006

Does your Palm shut off right when you're in the middle of something important?

Don't you hate how Palm's AutoOff feature has only a few options to choose from?

Well, these problems and more will be solved with SetAutoOff. SetAutoOff is the easiest and most customizable program that allows you to change the settings of Palm's AutoOff features.

Instead of just having a couple of options to choose from, now you can have many different options! You can have your pda shut off after just 3 seconds of inactivity, all the way to 60 minutes. Also, you can disable the AutoOff feature by setting it to 0 minutes and 0 seconds.

So, now you can watch a slideshow or read an ebook on your pda without having to worry if your pda will automatically shut off unexpectedly.
