> all if you manage to give me good feedback on how to do a better presentation next time around.

You really should ask the audience that question.

What a web based tool could do is integrate a feedback mechanism, maybe even tied to specific slides. Imagine you are giving the presentation, and I am bored to tears by your slide on profit margins increasing in Q2.

So I open the synchronized viewer app on my phone, and touch the frownie face icon or the icon that says 'zzzz'. Hopefully you will replace the bullets with an animated chart for your next presentation.

Maybe there already is an app for that?
