I've been using Apple Keynote for the past few years. Very effective, very powerful. It's my go-to presentation app. However, I need something more powerful than Keynote, in a sense that I can animate slides instead of being still at a time, more advanced control over slide transition animations, and so on.
I've tried the following:
- Microsoft PowerPoint
- Google's Presentation App
And none so far has been able to deliver Keynote's flexibility and power, let alone more advanced animation tools.
Preferably an app that professionals use, like what Google uses in their I/O, or Samsung in their keynotes, and so on.
I use macOS Sierra, and I have a very flexible budget that should cover any presentation tool.
