This sector still needs a leader...
It would seem to me that there would be dozens of slide show apps - the ipad is such a natural interface for this sort of thing and the included Photo app is so woefully inadequate.
This app takes a stab but is very unstable.
I am able to load portrait photos fine but if you try and load too many it just crashes and nothing is saved.
The transitions are fine but there should be a way to set the same transition for all slides without having to do each one individually. Unfortunately software developers seem to love random transitions a lot more than people looking at your holiday photos. The text feature is a welcome addition. The music track is an expected and usable feature. The zoom and pan works well. Many full scale slide show apps let you control the zoom and oan but it is not necessary at this level.
I think the slide sorting interface should be a full screen grid instead of the limited line on the bottom - moving a slide in a big show is too slow.
With so many mainstream PC (and I assume Mac) slide show apps to copy I am surprised there is not a killer app in this segment. I am still waiting for an iPad version of ProShow or something similar.
