戒指尺寸儀

This app is amazing and really helpful. It gives accurate measurements and doesn't take up much storage space. It definitely deserves a five-star rating.

After calibrating the app you are ready to go. It tells you how to measure your finger as well as rings and it works great all the time.

A simple to use app with nice application and graphics. After trying a few ones, I find this one the most precise and accurate app for measuring a ring size.

I have nothing but praise for this app. The app makes working out your ring size super easy and quick, all from your smartphone.
