Alzheimer's disease (AD) is progressive, neurodegenerative, causes dementia and is currently incurable. There are treatments for AD, but several recent studies have focussed on forms of prevention. Measures such as avoiding risk factors for other diseases, healthy habits and cognitive stimuli can help reduce the incidence of AD. Activities aided by technological devices can contribute to the prevention of this disease, such as logic games in the form of smartphone applications. This paper therefore presents a description of the functionalities of an application project for mobile devices that provides support for AD prevention activities. The app is defined through games and exercises that stimulate the fight against AD risk factors, covering physical and cognitive activities, meditation, social interaction and healthy lifestyle habits. To ensure motivation, greater player interaction and long-term use of the app, the introduction of a proposal to monitor and follow up the user using performance data and gamification could offer a greater chance of success in preventing AD.
