Ring Sizer: Risi

Very accurate and saves time trying to figure out where that soft tape measure is. Totally recommend. Simple so that's worth keeping as part of your things inn your pocket or purse. Excellent job! I have a few other apps on long this longer if you're interested. Would love to collaborate if possible. Thanks again! GREAT DEVELOPER!

Makes dealing with conversions from the standard US ring sizes to all international standards a breeze. I use this on a daily basis for my company, which is a jewelry B2B.

But accuracy will never be the same as a proper measurement. If you want a ring to be a surprise then secretly borrowing one of your loved one’s ring or using this app are the two best options. The app is super simple to use and makes measuring your ring size really convenient. I’m not entirely sure how accurate it is, but it’s definitely a helpful tool if you want an estimate without having to visit a jeweler. Overall, a great option to try!
