soft question – Math beamer presentations on iPad

Does anyone know of an app on the iPad which I can use for beamer presentations? I need one that

(1) Has the option of turning OFF the animated page turn (so that you can reveal the pdf as you would normally do in a math presentation)

(2) Has good annotation ability (for example has a laser pointer).

Point (1) seems to be incredibly hard to find, hence my asking on here. Thanks!
