Frequently asked questions

How do I choose my size?

Sizes 6 to 13. If you know your ring size, order that size. If not, wrap a soft tape measure around the base of the finger, or measure the inside of a ring that fits with a ruler, and match the number on our sizing guide. Between two sizes, take the smaller one.

If it arrives in the wrong size, we swap it free.

How long does the battery last?

6 to 11 days on one charge, depending on your size and how often you light the screen.

Which finger should I wear it on?

Index or middle finger reads best. Ring finger works too. Keep it snug, with the sensors on the palm side.

What shows on the ring?

Time, steps, heart rate, blood oxygen, hours slept, caller ID, timer, find your phone and remote camera.

Is the screen always on?

No. Tap to light it, then it goes dark on its own. When a call comes in it buzzes and lights up by itself. That's how it lasts up to 11 days.

Does it work with my phone?

Yes. iPhone and Android, through the Kalio app.

Can I shower and swim with it?

Yes. Water resistant to 50 m. Shower, swim and wash up with it on.

What if I don't love it?

Wear it for 30 days. If it isn't the easiest way you've ever checked your numbers, send it back for every dollar. That's the 30-day satisfaction guarantee.

After that, a 1-year warranty covers the ring.
