Circlet
Measure a ring, share the size.
Set any ring you already own on the screen and match the inside edges. No ring? A strip of paper and Circlet's true-scale ruler. Every size system, a card to send to whoever is buying, and nothing leaves your phone.
What it does
- Measures with a ring you own, or a finger with a paper strip
- US, UK, EU/ISO, Japan, and Italian sizes, plus millimetres
- Knows your screen's density; a bank card calibrates any it doesn't
- Share a card with the size and the wearer's preferences, or ask someone for theirs
One price, once
Measuring is free. Everything else, every size system, the no-ring method, unlimited saved sizes, is a single purchase. Never ads. Never a subscription.
