About

Ring Sizer

Features
Read full description

Ring Sizer is a simple tool for checking ring size directly on your iPhone. Open the app, place a ring on the screen, and adjust the circle with the smooth slider until it matches the inside edge of the ring. The selected size and inner diameter are shown clearly, so you can check the result without searching through conversion tables. The app supports JP, US, EU, and UK size systems. It automatically chooses a default based on your device language and region, and you can change it anytime from the size menu. The slider moves by size steps with subtle haptic feedback, making the measuring experience quick and satisfying. You can also save sizes for your own fingers. Store sizes for the left and right hand, from thumb to little finger, and review them later in the My Fingers tab. Ring Sizer is designed with a calm, feminine beige style that keeps the measuring circle easy to see while still feeling polished. It is perfect for checking rings at home, comparing sizes before shopping, or keeping a personal ring-size note.
