The Ray is our first product, a self-powered health and fitness tracker made for everybody. It measures sleep, heart rate, temperature, light exposure, and more, syncing your data with a companion smartphone app so you can live your healthiest life, hassle-free.

We are only manufacturing a limited run and expect to start shipping orders in April 2026. Your preorder guarantees you one of the first Ray devices and can be fully refunded for any reason, whenever you like.
