I am a ProPresenter user. It is robust and meets all my needs, but it comes with a pretty steep price. If your church owns a site license, ask them for the download code, otherwise it will cost your budget $399. If you are looking for a more affordable option and you have “been there done that” with PowerPoint and Keynote I recommend you try Prezi. I have always liked the idea of using Prezi. It is visually pleasing and pretty easy to use.
When I needed to be mobile with my presentations (meaning I had to use my iPhone or iPad) I use Apple’s Keynote, it was inexpensive, easy to edit “on the go,” and bonus…there was an iOS remote app. I will be giving Prezi a shot at a couple “on the go” presentations now…Why now?
Well, I just noticed (not sure when they had the official update) that Prezi has finally added an iPad edit/create feature with templates. Previous versions were only viewers, you could only play presentations that were created on your computer. Now I can create a presentation from start to finish directly on my iPad. It is easier to navigate and create from a computer, but if I need to correct a misspelllllingg or need to add a slide I can fix it from my iPad. By the way, Prezi is FREE.
