Why is the GeroSense app free?

GeroSense earns money by selling its API and providing services to business clients like the National University of Singapore and Humanity.

We developed the GeroSense application as proof that wearable data can be used to track users' biological age and measure the effects of different longevity interventions. We use this data to test our hypothesis, improve our models, and strengthen our understanding of aging. In return, we provide our service to end users for free.

Users' data collected from the GeroSense mobile application is not sold to third parties under any circumstances.
