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. IN-APP PURCHASE Ring Sizer Pro is a one-time purchase, not a subscription. You pay once, nothing renews, and there is nothing to cancel. - Payment is charged to your Apple ID at confirmation of purchase. - The purchase stays on your Apple ID and can be restored on any device from Settings inside the app. - Measuring a ring is free and stays free. Pro is never required to get a size. Terms of Use (EULA): https://abouchfa.com/terms Privacy Policy: https://abouchfa.com/privacy
