I am not 100 % sure what you mean by online PT software. We have purchased a number of years ago the BodyMap from NASM which is an assessment tool.
Personally, I do not use the automated version even though I use the grid and follow the assessment recommendations. My reason is because I simply do not like the “if this, then that” mandate that it generates. While the printouts are very nice and professional, I prefer to do it my own way. However, you can check it out and see an example following this link which you may have to copy and paste because it does not want to come up properly.
