iOS: Alfred is best known as a supercharged application launcher. However, if keyboard shortcuts aren't always your thing, the new iOS app controls all your Alfred action from a remote app.
The app itself simply works as a trigger. You can customise what Alfred action appears in the app, then trigger them with a tap. Setup requires that you have Alfred installed and running on your Mac, and you'll need to pair the two apps together from the Mac app. As far as the basics go, you can launch apps, search the web and use system commands from your iOS device. If you're a Powerpack user, you can also control iTunes, trigger workflows and paste clipboard snippets. If you're an Alfred user, it's a great extension to the app.
