Yes. It carries a 5 ATM rating, which covers swimming and showering. Avoid high-pressure water and hot tubs.

Does it work with Android and iPhone?

Yes. It is listed as compatible with both iPhone and Android through the companion app.

Yes. Sleep tracking is one of its listed features, and a ring is easier to wear overnight than a watch.

Do I need a subscription?

That depends on the brand's app. Check whether full sleep and activity insights require a paid plan before buying.

Fit matters for sensor accuracy. Use the brand's sizing kit or measure your finger, and wear it on a finger that does not swell much.

It is better for passive, all-day wear and sleep. A watch gives a screen, live stats and GPS, which this ring does not.
