Ring Sizer: Size Measure

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.
