List of desired qualities not implemented in the app development.

Domain	Details	The rationale behind not implementing other desired qualities
Accessibility	Voice-overs in the chatbot Multilingual functionalities	Developing functionality in the chatbot builder for automated voice-over generation (budgetary constraints) Developing a multilingual app would require additional efforts (budgetary constraints)
Adaptability	Adapting to the user’s habits	The solution would require developing a complex framework for passive and active data collected in the app (timeline constraints)
Autonomy	Free-text conversation	The solution would require resource-intensive training in AIa-based tools such as Rasa for free-text conversations. Free-text automated conversations may be prone to faulty health advice, and the provenance of the advice may be unclear (AI “black box”)
Gamification	Incentives	The solution would require either additional financial capability or intense efforts to build partnerships that would provide vouchers
Guidance	Medication management tool Carbohydrates calculator Exercise tracking BGLb calculator	The solutions would require developing separate passive and active data collection modules in the app (budgetary constraints); they would also require developing complex evidence-based rules for feedback, taking into consideration individual health constraints
Integration	Chatbot connected to a human	The solutions would require hiring trained diabetes consultants available daily for the users (budgetary constraints)
Personalization	Condition severity Age Sex	The solutions would require developing additional app modules that would show different content according to a selected variable (budgetary constraints)
