When I used ExploreStars for scope movement, I found using the “compass rose” as an easier alternative to the up/down/left/right buttons.
With just a little practice, you can keep your finger on the center of the rose, and move the scope, without removing your finger or your eye from the eyepiece. It also functions in a slower/faster rate depending on finger movements.
