Launch Center Pro is an automation utility for the iPhone. You launch the app, then choose an action that you’ve configured earlier. Most actions in some way interact with other apps you’ve installed on your iPhone. For example, say you copied some text in Safari; you can have an action set up that takes the text from the clipboard and uses it to automatically Tweet that text. Or send it to Evernote as a new note. Or send it as a text to your spouse.
This app isn’t for everyone, but I love utilities like this and it’s extremely well done. I owned the original Launch Center and hesitated on having to buy a new version so soon after the original, but this version is so much better and it was completely worth it.
