I'm still trying to figure out what your product does, and how it works. Questions that come to mind at first glance (although I'm sure I can reason some through, and take guesses... and probably think of more):

- I just download this onto my phone?

- Where would the presentation be stored?

- What do I have to do on the presenting machine?

- What does the remote look like?

- Is the remote going to force my screen not to lock?

- Will my screen be bright and distracting to my audience?

- Why is there no information? Is this malware?

- How do I get rid of the Tip box which is covering text, because I'm using 200% zoom on Retina?

- Why is there a log in? There's no accompanying register.

- What software does this work for?

Also, your logo is really fuzzy, and your HRs don't match up... but that's just me being picky!
