## What is Ring Sizer?

Most ring sizer apps use a generic circle on every phone. Screens vary in size, so the number it gives you is a guess. That's why reviews often say, "it said 10, it was 7." This app computes real millimeters from your exact device screen. Lay a ring you already own flat on the glass, size the glowing disc to its inner hole, and read your size.

KEY FEATURES
- Real millimeters, not screen points: the disc is sized to your device's actual screen, so what you see is the actual size.
- Verify accuracy: place a bank card against the screen to confirm the scale in about ten seconds.
- Your own size system on every result, free. All nine at once with Pro: US and Canada, UK and Australia, EU and ISO, Japan and Korea, China, India, Germany and the Netherlands, Italy and Spain, Russia.
- Accurate results: each reading includes a tolerance band, and the app flags unlikely numbers instead of guessing.
- Save one person's sizes free, or every person and finger with Pro, with a measurement log and median reading.
- Eight concise guides, all free, cover wide bands, large knuckles, resizing, and daily size fluctuations.

WHO IT IS FOR
Whether you're buying a ring online, ordering from another country's sizing system, sorting inherited jewelry, deciding whether to resize a band, or discreetly sizing a partner's finger before a proposal, this app gives you a verifiable number.

WORKS WITH
Wedding bands, engagement rings, signet rings, stacking rings, wide bands, vintage and inherited rings.

FREE AND PRO
Measuring a ring is free, unlimited, and always will be, and every result shows your own size system plus ISO. The bank-card accuracy check, the tolerance band, all eight guides, and one saved profile are free too. No ads and no account: all your measurements stay on your device.

Pro unlocks all nine systems on every result, the no-ring finger method, fit advice for wide bands and large knuckles, the full conversion chart, a printable paper sizer, an on-screen millimeter ruler, a shareable size card, saved sizes for everyone and every finger, and the discreet partner sizing kit.
