Frequently Asked Questions

Can I use my HSA or FSA card to buy an Oura Ring Gen 4?

Yes—both the Oura Ring hardware and multi-year membership bundles are 100% HSA and FSA eligible at checkout.

Why does Oura Ring measure from the finger instead of the wrist?

The palmar arteries on the underside of your finger sit much closer to the skin surface than wrist capillaries, producing cleaner overnight pulse and temperature signals.
