I would give it no stars if I could! It sucks! Can't zoom in to select data points, not nearly as good as the Apple version. I already rated it 1 star and it keeps saying 'Please rate me.' Don't install! Beware!
Too hard to align points of scale, once they're down you can't move them, have to go back to the beginning and start over. Nice idea, too many problems
