Keynote is the most powerful presentation app ever designed for a mobile device. Built from the ground up for iPad, iPhone, and iPod touch, it makes creating a world-class presentation — complete with animated charts and transitions — as simple as touching and tapping. Use full-screen view to present right on your iPad, iPhone, or iPod touch. Or use video mirroring to present it on an HDTV, and preview your slides and notes on your device using the presenter display. Keynote works with iCloud, so your presentations stay up to date across all your iOS devices — automatically.
