Here are some things I like about this app:
- There is an internal image search that seeks out high-resolution copyright free images without going outside the app.
- Text is limited so that the app really serves as a visual tool to engage viewers.
- Presentations may be stored online as video slides by setting up a free account.
- The app is free (there are some purchase opportunities for new slide templates inside the app, but the program provides five initial templates -- more than enough for one to get started).
- One is also able to incorporate video into the presentations. See this article for information on how to do this.
Here are a couple additional Haiku Deck resources:
