FAQ

What does the Ring Sizer Tool do?

The Ring Sizer Tool helps you accurately determine your ring size. It allows you to measure your finger directly or compare an existing ring to find the perfect fit, eliminating guesswork for online purchases.

How does the app measure ring size?

The app offers two primary methods: you can use it to measure your finger directly for a precise fit, or you can use it to measure an existing ring you own to find its corresponding size. This ensures accuracy whether you have a ring to compare or not.

Is the Ring Sizer Tool free to use?

Access to all features, content, and functionality requires an annual auto-renewable subscription. This subscription is charged to your iTunes Account upon purchase and automatically renews unless canceled at least 24 hours before the end of the current subscription period.

Who is the Ring Sizer Tool for?

This app is designed for a wide range of users, from individuals who occasionally buy rings online and want to ensure a perfect fit, to expert jewelers who need a reliable tool for precise measurements. It provides confidence for all online ring selections.

Can I use this app if I don't have a ring to measure?

Yes, absolutely. The app is specifically designed to work even if you don't have a ring for comparison. It offers a feature for spot-on finger measurements, ensuring you can still achieve an impeccable fit.
