About us

Sanva was built on a simple idea: understanding your body shouldn't come with a $300 price tag or a monthly subscription. The Sanva Smart Ring tracks the metrics that matter, heart rate, sleep, blood oxygen, HRV, and stress, in a device that looks and feels like the jewelry you already wear. No app fees, no renewals, no surprises. Just one ring, one price, and real data you can actually use.

Most health wearables lock your data behind a $300 price tag and a monthly subscription. We built the Sanva Smart Ring to change that. Every ring tracks the metrics that actually matter, heart rate, sleep, blood oxygen, HRV, and stress, without an app fee standing between you and your own data. No recurring charges, no upsells. Just one ring, built to work for as long as you wear it.

Sanva exists because health tracking shouldn't be complicated or expensive. We wanted a way to understand your body that fits into real life, not another gadget to charge every night or another app asking for your credit card. The Sanva Smart Ring gives you the same core health data as devices costing five times more, in a design light enough to forget you're wearing it. That's the purpose: real data, real simplicity, at a price that makes sense.
