Quick answers

The questions we get most — you might find yours here.

How do I choose my size?
Wrap a strip of paper around the base of your finger, mark where it overlaps and measure it in millimetres. Match that to the size chart on the product page (sizes 8–14). It should sit snug, just above the knuckle.
Where is my order?
You'll receive a tracking link by email as soon as your ring ships. If it hasn't arrived, send us your order number using the form above and we'll track it for you.
Do I need a subscription?
Never. Every feature and the companion app are included — no monthly fees, ever.
Can I return it?
Yes. Try Kevenza for 30 days. If it's not for you, contact us for a hassle-free return and a full refund.
Does it work with my phone?
Yes — the free companion app works with both iOS and Android.
