I've been looking for a scorekeeping app on the phone that I like. None of the ones that are free are very good, but I think that Baseball ScoreBook Lite shows some promise. Pretty straightforward, can import up-to-date lineups, easy to remove mistakes.
But I've recently decided that maybe I can just adopt a drawing app that can load a picture/file/scoresheet as a background to draw on so that it feels more like pen-and-paper scoring. Just needs a zoom in/out function along with the drawing.
Unfortunately the 3 or so that I tried loses so much resolution when I import the scoresheet that this idea isn't panning out...yet.
