I would like to gain/coach some of my clients online.
I will need to conduct a fitness assessment questionnaire and PAR-Q in order to personalize their program and also to gain clients. Also, I would like to coach them through this app to if possible.
I am on a shoestring budget and need to know what free or low cost apps/online services are available for me. I understand if I will need 2 apps but one is preferred.

Thanks a lot!
