I'm looking for an iPad app that I can use for my PDF presentations. The absolute must-have features are:
Good annotation support.
I'm giving 2hr lectures so I have to be able to write on the presentation in response to the students' questions, or to highlight something that I want the students to take particular note of.
No annoying page transitions.
Since the presentation is a PDF, incrementing information on a slide is actually handled by having a whole new page which is almost a copy of the previous one. So when changing pages, the students' attention has to be on what just changed on the slide, not on some fancy page turning or sliding feature.
GoodReader has the second feature, but it's annotation support is somewhat limited. In particular, freehand writing is difficult.
There are many PDF annotation apps that have the first, but I've yet to find one that has (almost) no page transitions. I had found eNote Taker which was acceptable (there's a slight blurring of the image on changing, but that's alright), but today it got upgraded to GoodNotes and now page turning is done by sliding (I have emailed GoodNotes to ask them to fix this, but my next lecture is tomorrow morning so even if they agree it's unlikely that it'll be fixed in time).
So my question: is there an iPad annotation tool without annoying page transitions?
Unfortunately, none of the reviews that I've found mention page transitions so I've been reduced to watching interminable youtube videos to try to see the transitions (that's how I found eNote Taker).
(I hope that this is an acceptable question; I've tried to make it non-subjective and with a clear potential answer. However, I'm not a frequent user of this site, so if it is not acceptable, I apologise in advance.)
