Chargerless
Chargerless makes Ray, a 7-gram health tracker that powers itself from light, so you never have to take it off or charge it. Ray tracks sleep, heart rate, HRV, temperature and activity around the clock, with no screen and no subscription. Founded in 2025, Chargerless builds wearables you put on once and keep on, so a dead battery never interrupts the picture of your health.
