Apple's Keynote Remote app now offered for free
Apple's iOS app, Keynote Remote, is now available at the App Store free of charge. Keynote Remote lets users control a Keynote presentation on one's Mac, iPad, iPhone or iPod touch from another iPhone or iPod touch in the room. Once priced at $1, Keynote Remote was Apple's last paid iOS app. According to Michael Grothaus at TUAW, it has not received an update since 2011, and still does not offer support for the iPhone 5 family's four-inch screen.
