Welcome to the forum, @MAARIF! We are really glad to have you join us.
You raise some interesting points. The CHT is certainly meant to support health care workers and not replace health training or the human interaction involved in providing care. It is also a reality that smartphone penetration is low in many communities. The CHT supports SMS forms that work with basic phones, through which users can interact with the system via SMS.
I’d encourage you to raise these topics and others for discussion in the implementation category. In case you have specific questions or comments about the tools, then the product category would be a great place to start.
