# Chargerless — Ray, the self-powered health tracker

> Ray is a featherweight wrist tracker that powers itself from light. No charger, ever. No subscription, ever. More sensors than a Whoop, in something you'd mistake for jewelry. Designed and assembled in America. $199 one-time.

Built by Andy Kong (MIT, ex-Google). Batch 1 (100 units) sold out within days; Batch 2 is reserving now and ships in September 2026. Hardware warranty included.

## Why this matters

Every other major health tracker on the market — Whoop, Apple Watch, Oura, Fitbit — requires recurring charging or a subscription, often both. Ray is the first wrist-worn fitness tracker that ends both rituals. It harvests energy from indoor and outdoor light, runs continuously on one minute of real sunlight per day, and lasts two months on a full charge in total darkness. It weighs 7 g and is designed to last 10+ years. Built in America by a team obsessed with making technology that disappears.
