This 9.99 app is the most popular iPad presentation system. 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. Highlight your data with stunning 3D bar, line, area, and pie charts, animated with new 3D chart builds such as Crane, Grow, Radial, and Rotate. Use full-screen view to present right on your iPad, iPhone, or iPod touch. Or use video mirroring to present on an HDTV, and preview your slides and notes on your device using the Presenter Display. The Retina display on the new iPad makes everything you do in Keynote even more brilliant. Keynote works with iCloud, so your presentations stay up to date on all your devices — automatically.
