iPhone: Launch Center Pro has long been one of the best launchers and automation tools on iOS. Today it gets a little better with the inclusion of a Today Widget where you can launch apps (and actions) right from the Notification Center.
You can add any launch action to the Notification Center that you want, including actions like calling a specific person, getting directions home in Google Maps, sending a message to person, or launching apps. Since Launch Center Pro supports over 100k apps, you can create little launchers for basically anything you'll need. The app's also on sale for just $6 right now.
