Smart Ring With No Subscription: What You Get With b.ring
Short answer: yes, there are smart rings you can use without a monthly subscription. Every b.ring smart ring includes all app features with the device — sleep, heart rate, HRV, blood oxygen (SpO2), stress and activity tracking — for $0 per month, forever.
Why the subscription question matters
Many smart rings unlock key features, such as detailed sleep analysis or health trends, only with a paid monthly plan. Over two or three years of use, that recurring fee can add up to more than the price of the ring itself. Before you buy any smart ring, check what still works if you never pay a subscription.
