I had used OnTarget back when I was able to make it run on my Mac. When that became troublesome, I switched over to Ballistic-X on iOS. It works in very much the same fashion and having it on the phone is also very handy. I guess it depends on what you're after; I know OnTarget had some database features. I only every used it for Group size and load development, which relied solely on pictures.
