Eli Health has launched the Hormometer, an at-home testing system that uses your smartphone camera to assess the hormone levels in your saliva. It sounds very futuristic in the sense that it is an advanced concept, but it is one for here and now thanks to the advances of Eli, with the company detailing five years of research and 12 pending patents. Now at CES 2025, the congregation point of tech enthusiasts and the latest generation of products, the event provides the backdrop for the unveiling of the Hormometer, starting with cortisol and progesterone tests. With a similar appearance to a pregnancy test, the device has a display window to view results.
