FAQ

Which fingers can I wear the ring on?

RingConn recommends the index finger for optimal sensing, but says accuracy remains consistent on the index, middle or ring finger.

How do I find my ring size?

Place the sensor on the palm side and wear the sizer snugly at the base of the finger. Try it for at least 24 hours, including overnight; if between sizes, RingConn recommends the smaller size. Support can help review fit photos or video.

Are Gen 2 and Gen 2 Air sizing kits interchangeable?

Yes. The two models use the same ring sizes and sizing kit.

How long does one charge last?

The product FAQ gives up to 10 days for sizes 6–7, 11 days for 8–11, and 12 days for 12–14. More frequent sleep-apnea monitoring can use additional power.

How is my health data protected?

RingConn says transmissions, stored data and analysis are encrypted and processed on AWS servers in the United Kingdom; see its privacy policy for the complete policy.

How do I move my data to a replacement ring?

One RingConn account supports one ring at a time. Unpair the old ring before pairing a replacement to keep account history, or use a separate account. RingConn advises against frequent account switching.

Does the ring monitor health continuously?

The FAQ says it continuously tracks heart rate, blood oxygen, body temperature, sleep, daily steps and exercise calories, among other metrics.

Can it track naps?

Yes. The FAQ says naps are included, with sleep-stage, breathing-interruption and blood-oxygen tracking.

Can I wear it while exercising?

RingConn lists running, cycling and yoga as suitable activities and rates the ring IP68 waterproof. Harder surfaces can scratch it.

Can I trade in a Gen 2 ring?

The product FAQ says Gen 2 is not currently included in the trade-in program and directs customers to support for more detail.

What charging accessory comes with Gen 2?

The order includes a ring-size-specific charging case for wireless charging and a USB-C cable. The separate charging dock is associated with Gen 2 Air, supports all ring sizes and uses wired charging.

Can I change the ring color after sizing?

For orders placed with “I don't know my size,” the FAQ says customers can update the color once after using the sizing kit and before submitting ring details in their account.
