Ive had this program on my iPad for some time now and have started referring to it once again only recently. Would that I had returned to it sooner. In between all the automatic updates, Ive tried other programs that have left me nearly bereft what with the flash of pictures and pretty graphs. I started looking through this application about a week ago and was very surprised and ecstatic, nearly, to see what updates had been taking place while I was "cheating" on this one.
Im still going through this App and experimenting with the plethora of options and real scientific datum available. Occasional crashes I can take knowing that the programmers are working out the bugs. Worth the money easily.
