With version 3.0, Launch Center Pro is now a universal app! That means the old iPad-only version of the app is now obsolete and has been removed from the App Store.

To upgrade to 3.0, first go to the current version of the iPad app and back it up. Then delete the app completely from your iPad. Now go to the App Store and install the new universal version of the app and restore your actions.

One thing to watch out for, if for some reason you don't delete the old version of the app, it crashes when you try to authenticate with Dropbox.
