Great question. StutterOn started off as a non-profit that would provide tools completely free of cost but as we got further into development, we realized this wasn't sustainable. Our pricing model is to give free access to all our tools and then have a small few if the user would like to use our tools for an extended amount of time- essentially a daily usage limit. For clinicians and enterprise use, the cost is higher. We focus more on the social and emotional aspects rather than fluency-enhancing as we know that stuttering isn't something that can just magically go away. We focus heavily on self-advocacy and affirmations, tying in a journal feature where users can put down any thoughts and feelings they have about their stutter. Hope this helps, if you have any other questions, let me know!
