Eterly is the world’s first health and fitness monitoring and recommendation app dedicated to overcoming the challenges of the ageing process and prolonging life expectancy. Eterly works by collecting and storing users’ personal health data securely in the blockchain, and combining it with the latest health and longevity research, using blockchain technology - all incentivised using digital tokens known as Lifecoins. Eterly uses AI driven machine learning and algorithmic techniques to provide personalised fitness advice, dietary, nutritional and medical recommendations and treatments to combat anti-aging diseases, disseminated through the app’s connected, interactive and user friendly interface.
