Themes for Keynote
contains an impressive collection of Keynote designs for your presentations. Every template can be used to create a content-rich and captivating presentation that will truly impress your audience. The collection is comprised of action themes with moving backgrounds and the regular themes with static backgrounds. Furthermore, all the templates are available in several different sizes--including full HD at 1920x1080 pixels--so everyone will find the perfect size for widescreen displays (16:9, 16:10), iPad (4:3) and different projectors. With iCloud, it is also easy to keep your presentations up to date across all your devices--including iPhone, iPad, and iPod Touch--so you can start your presentation on the Mac and then access the latest version of it on whatever device you happen to be using at the time.
Note: Though the themes are free to download, they have to be unlocked through in-app purchases.
