Lumo started with a simple frustration: the best sleep trackers cost as much as a phone and then charge a monthly fee to show you your own data.
We think a good night's sleep should not come with a subscription. So we built a ring that does the essentials well, sleep, heart rate, blood oxygen, temperature and activity, in a slim stainless steel band with a battery that lasts days and a case that keeps it charged for weeks.
Every ring ships from the United States, comes with a charging case and cable, and is covered by a 30-day fit guarantee and a 12-month warranty.
