Ring Sizer is a convenient and reliable iPhone app developed by H.W.E. DOO that provides a digital solution for determining the accurate size of your ring or finger. With this app, you can easily measure your ring size using your phone.

To use Ring Sizer, simply place your ring on the circle provided and align the edge of the circle with the inner edge of your ring. The app will then display the size of the ring in different measurement systems, including US/CA, AU/GB, EU/ISO, and JP/CN. You can also use a ruler for measuring rings and other items.

In addition to the basic features, Ring Sizer offers a Premium Plan subscription option. This subscription provides unlimited access to measure your finger or ring and view all ring sizes. The subscription auto-renews at the end of each period, and payment will be charged to your iTunes Account. You can manage your subscription and turn off auto-renewal in your Account Settings. It's important to note that any unused portion of a free trial period will be forfeited if you purchase a subscription.
