to create something different than a PowerPoint, just to change things up. PowerPoints and Google Slides are the old standby, of course, but if there is something else that is free and that makes it look nice and is easy, why not?
Haiku Deck, a free app for iPad and a free account on the web that can be used to make dynamic and beautiful presentations. One of the reasons I like it is because the images you use are within the app and can be used without the risk of violating copyright. It's also an easy program to introduce to students so they can build dynamic presentations for a class project.
autosaves and the images within the presentation are gorgeous. A student or a teacher can create some very dynamic and beautiful presentations.
One thing to note; you cannot import your own images. You can embed a chart with data but all the images you use come from within the app. If you are doing a specific presentation, you may not be able to find all of the images you are looking for. If you are looking for a different way to make a presentation, Haiku Deck is a free way to do so. The images alone are worth a stop to the site.
