Don't get me wrong, I do love Keynote. I was one of those who actually paid for it way back when I got one of those original iPads. And then Prezi came along and blew our minds. And finally, Microsoft (finally) gave us a pretty darn good version of PowerPoint – which I also use – often, and shamelessly. They're really great apps, all three of them.
But there are a few other really good presentation apps out there which you can use to build engaging content.
(Note: There are one or two other apps that do what these do, but I am not recommending them because I find them either too unreliable or difficult to use.)
In no particular order:
Why? Because it's collaborative. Slides should actually be classified with Keynote, PowerPoint and Prezi, but it isn't generally used by as many people, in my limited experience. And it should be.
You know when you wished you could just put a presentation together and have the programme find images and design everything nicely for you. Haiku Deck does.
Another seriously cool and easy to use Adobe app.
VideoScribe should have been everyone's go-to presentation app. It should have been an essential on everyone's iPad. But, alas, they were slow to respond to the original app's failings. VideoScribe Anywhere is a more user-friendly version. It still has its problems, but when you pull it off, your presentations will look seriously awesome. I still love it, despite its problems and low rating on the App Store. Works best as part of an appsmash project.
