The Hyfe Story

Hyfe is a team collaboration between people and institutions who contribute their skills and experience to build a tool that can help individuals and health professionals track cough as part of wider public health efforts.

The cough tracker was not originally designed for Covid19. But the pandemic accelerated the team’s decision to get it to market fast as we believe cough tracking - identification, quantification, and eventually disease classification - to help  people stay on top of their health and a potentially impactful tool in the global response to public health crises.

Hyfe is an impact-first initiative. This tool does not monetize anything and is not making any money. It is currently self-funded and the team is actively trying to identify sufficient funds to keep it free to use and eliminate any monetization pressure.

The team is committed to provide a perpetual free-to-use license of this tool to any public health institution that would like to deploy it in their own efforts as well as a perpetual free-to-use license across low and middle income countries.
