RingConn Gen 2 Smart Ring [Size: 13] – Sleep Breathing Insights, 12-Day Battery

Watch the full review

Please note: this ring is size 13, in the gold finish. A smart ring only reads accurately when it fits, so check your finger against a size 13 before ordering — the sensors need firm contact with the skin.

A smartwatch you take off at night is not tracking your nights. The RingConn Gen 2 is a health tracker you forget you are wearing: it reads sleep, heart rate, stress and recovery around the clock, and it charges once every twelve days.

Sleep breathing insights, night after night

This is the feature the Gen 2 was built around. It watches your breathing patterns across whole nights and turns them into plain summaries in the app, so you see a trend over weeks rather than one confusing chart. If your sleep has felt broken without an obvious reason, this is where the reason shows up.

No subscription, ever

Every feature, every report, all your history — no monthly fee, no paywalled insights. Most of the ring’s competitors charge for the app, and over a couple of years that subscription costs more than the ring did. Firmware updates arrive over the air and keep adding to it.

Twelve days between charges

A watch you charge nightly is a watch that misses your sleep data. Twelve days means you charge it while you shower on a Sunday and forget about it again.

It tracks more than sleep

Heart rate and HRV, blood oxygen trends, daily activity, stress load and women’s health cycle tracking — all in one app, on Android or iOS.

Built to stay on your hand

Waterproof to 100 metres, so it stays on through showers, washing up, workouts and swimming. The finish is smooth and skin-friendly, and it is light enough that most people stop noticing it within a day — which is the entire point of a ring over a watch.
