SaveCircle is a little tool that can save in chosen time the document of the frontmost application, so that you don't have to worry about loosing some work.
SaveCircle will replace the old "cmd-s" combination, avoiding you killing your keyboard by frenetically saving your work.
You can do everything from the main window: turn the software on/off, detach the countdown or change save options.
You want more integration? The countdown can be showed into the menubar. Really usefull to see everywhere when the next save take effect!
The countdown can be detached. So, you can integrate it with every front application.
