Dementia and Alzheimer's disease are affecting more and more people worldwide. According to the World Health Organization, 60-70% of the approximately 55 million people diagnosed with dementia worldwide suffer from Alzheimer's, adding 9.9 million new cases diagnosed each year. While the annual global cost of dementia exceeds $1 billion, its cost is estimated to double by 2030.
 It is stated that new digital technologies and e-health solutions for dementia patients have a strong potential to help individuals face the challenges related to dementia and neurodegenerative disorders. Some examples of e-health solutions for people with dementia are reported as wearable, portable, or implantable devices, depending on appropriate platforms and services, and to support interaction between patients and doctors. New digital technologies are powerful tools to help individuals overcome the challenges of dementia and neurodegenerative disorders. Communication difficulties are common in people with dementia. Meaningful communication initiatives using technology and the Internet can help alleviate symptoms and perhaps lessen their severity. To develop and implement this potential, it is essential to produce solutions that combine health sciences, social sciences, and engineering solutions. With the idea of REMEM, developed with this in mind, with the support of the Turkish National Agency and the European Union, mobile applications aimed at improving memory that can be used not only by dementia and Alzheimer's patients but also by others were examined and a new mobile application called REMEM was developed.
