 Fitness enthusiasts, flow state seekers, bio-hackers, and more are constantly looking for new tools to help them calculate and analyze their metrics. Now a new smartphone app seeks to not only use this data to gauge biological aging, but also possibly help slow down or even reverse it. The app, called Humanity, aims to help users make optimal lifestyle choices that could impact their health and longevity. Once registered on the app, users enter basic information such as age, weight, and height. The app can connect to phone sensors and wearables to track a variety of biomarkers, such as heart rate, walking distance, and sleep quality. Based on this information, users are given a Humanity score, or H score, in four different categories – movement, mind, recovery, and nutrition. The app will then make suggestions, and over time, users may see their H score slowed or reversed. Founders Michael Gere and Pete Ward have been developing the app for over two years and have raised $5 million in funding from investors. According to Ward, we saw a major issue with most health and longevity apps – that even once you might get a good reading of your biological age, you were left on your own to figure out how to change it, so we set out to make that the main focus of Humanity. Much like a traffic navigation app advises you on where to turn to get to your destination faster, Humanity uses similar data techniques to guide you to better health and longer health span faster. The founders say that Humanity doesn't simply adjust users' biological ages because they exercised, for example, instead it compares that information against data drawn from a scientific database. As for privacy and security, the creators say that the app stores as much information locally on your phone as it can and runs its algorithms as much as possible on your device. The company says that any data that does go to its servers is encrypted during transmission in storage and that it keeps its data private. Humanity is now available on the iPhone app store in the United Kingdom and a global launch is planned for September and Android version is also being developed. There is a free version available, but if you want the added features that enable continuous monitoring of your health data, you will need to choose the premium subscription service, which costs around 30 British pounds a year in the UK version, which is around 41 US dollars. Premium users will be able to watch their biomarkers and discover how their actions change their biological ages, but not so fast. Humanity is currently rolling out full access to the app on an invite-only basis. To gain admission to the closed beta, you can request access on their website at humanity.health.
