QUIET TECHNOLOGY, DAILY CONTEXT

Small ring. A clearer rhythm.

Turn a number into one useful decision

Start with a question you can act on: does a steadier bedtime fit your week, or do busy evenings leave less room for rest? Review several days together, add context from your own life and change one habit at a time. A low score is information to consider, not an instruction to abandon your plans. This is a suggested way to use the product, not a personal test or a promise of a health outcome.

Designed to stay on

The titanium model weighs 3.3–5.2 g, depending on size, and has recessed interior sensors. Choose the Ring 4 sizing kit before selecting among sizes 4–15; a familiar jewelry size is not a reliable shortcut.

A longer view

Sleep, Readiness and Activity scores create a daily starting point. Active membership adds detailed trends and insights in the companion app. Consistent wear gives you more context than checking only after an unusually good or bad night.

Make charging ordinary

Official typical battery life is 5–8 days, with charging usually taking 20–80 minutes depending on the starting level. Size, enabled features, use and battery age affect results. Choose a repeatable charging moment so a depleted ring does not interrupt your routine.

Before the day begins

Open the app, glance at your recent pattern and choose one manageable priority. Keep your own energy and commitments in the picture; the score does not know your whole day.

Budget for the whole experience

In the US, membership is $5.99/month or $69.99/year before applicable tax, with one included month for new members. Regional prices and payment requirements differ.

Keep the routine comfortable

Clean and dry the ring and the skin beneath it, and follow Oura's care guidance. Its 100 m water-resistance rating is not permission for scuba diving. Remove it when an activity makes the fit uncomfortable or risks catching the ring.

Can I use it without membership?

Yes, but the app is limited to the three daily scores and basic functions. Detailed trends and insights require active membership; consider that ongoing cost before choosing the ring.

Is this the ceramic model?

This page describes titanium Oura Ring 4. Ring 4 Ceramic uses a different outer material and has different weight and thickness. Confirm the exact listing rather than assuming every Ring 4 finish has identical construction.
