So the firs thing I wonder about this is not what the price will be, but how will you get mental health providers to integrate the app into their workflow? What is the ROI specifically that would make a company want to buy this? How can you justify the cost with the value provided? Is this something that can be billled for? What is the entire interaction between the patient and the doctor? Is the doctor going to get paid for using this? What is the benefit to the provider for implementing this? Once you understand the perspectives and experiences of every individual who is touching the product then you can start thinking about price.
