Circlet

Circlet measures ring size the way a jeweller does, with nothing to buy and nothing to sign up for. SET A RING ON THE SCREEN Put any ring you already own on the drawn one and match the inside edges. Drag the bead, pinch, or scrub the millimetre ruler. Your size appears instantly in your own country's system. NO RING? NO PROBLEM Wrap a strip of paper around the finger, mark it, and lay it on Circlet's true-scale ruler. Honest guidance on the knuckle, the time of day, and the weather โ the things that make other apps "not accurate." EVERY SIZE SYSTEM US and Canada, UK and Australia, EU/ISO, Japan and China, Italy and Spain โ plus the millimetres, which never lie. SEND IT TO WHOEVER IS BUYING Share a card with the size in every system and the wearer's preferences: metal, stone, a note. Or ask someone for their size with one message. Rings are bought by one person for another; Circlet is built for both. ACCURATE ON ANY iPHONE OR iPAD Circlet knows your screen's pixel density. If it doesn't, lay a bank card on the screen once and it will. ONE PRICE, ONCE Measuring is free. Everything else โ every size system, the no-ring method, unlimited saved sizes โ is a single purchase. Never ads. Never a subscription. Nothing leaves your phone. Circlet is made by Country Boy Creative.

The clearest difference is ads: Circlet at none against Ring Sizer's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
