Participants rated eight features of a potential dementia care support app according to the Kano technique. Out of the eight product features investigated, six were positively associated with an application (wandering detection, weather and other threat detection, notifications and voice prompts, location sharing, emergency services contact, and medical records). The median for the amount people were willing to pay per month was 25$ (CanD) with a third quartile of 50$ (CanD).
