If you can’t find an app for your Mac that does what you want, take Edward Mendelson’s advice and build your own using Automator.
You use Automator to create an app that performs exactly the series of steps that you want it to perform. Each step gets performed by a kind of building block called an Action; the full sequence of steps is called a Workflow. You can save a Workflow as a standalone application that runs when you double-click it, or you can save it as any of various other kinds of OS X utilities, including Calendar Alarms and Services—a Service being Apple’s name for a utility program that runs only from menus and pop-up menus in other OS X applications, not as a separate app that you run by double-clicking it in the Finder.
Warning. The article is extensive and spread over multiple pages which means more ads to view, but you’ll find more to like about Automator in OS X.
