The Mind Guardian is an innovative AI-based screening tool designed for individuals over 55, aimed at early detection of cognitive decline. This free Android app features three engaging missions that simulate various cognitive tasks, utilizing established psychometric tests to evaluate memory and mental agility. Users navigate through a virtual city that mirrors their cognitive landscape, providing a unique way to explore and assess their mental faculties.

Each mission offers a distinct challenge: from recalling memories in 'A Walk to Remember' to enhancing coordination in 'The Circle of Time,' and finally, strengthening semantic memory in 'The Album of Your Memories.' With scientific backing from reputable organizations, The Mind Guardian not only promotes cognitive health but also allows users to anonymously contribute data to enhance research on cognitive decline. The app is available in Spanish and optimized for Android tablets, requiring version 8 or higher.
