## What is Mila's Ring Sizer & Converter?

From the developer of Mila's Tools (Apple Staff Pick, 1,200+ reviews at 4.8).

Find your perfect ring size in seconds. Seven international sizing systems on one screen — no charts to memorize, no guesswork.

Mila's Ring Sizer & Converter is the standalone version of the ring sizing tool from Mila's Tools, the 29-category unit converter on the App Store since 2011. Type any size and every other standard updates in real time:

* Inner Diameter (mm)
* Inner Circumference (mm)
* US Ring Sizes
* EU (Continental) Ring Sizes
* UK Ring Sizes (A–Z, with half sizes)
* Swiss Ring Sizes
* Japanese Ring Sizes
* Chinese (Mainland) Ring Sizes
* Hong Kong Ring Sizes

Don't know your size? Measure directly from your phone:

* Match a Ring on Screen — lay a ring on the display and tap the circle that fits. US sizes 3 through 15 in half-size steps.
* Measure with String — wrap a strip of paper around your finger, then read the length on a calibrated on-screen ruler accurate to 0.5 mm.

A one-time screen calibration with a common coin ensures physical accuracy. 13 reference coins from major currencies are included — the app picks the right one for your region.

Whether you're shopping for an engagement ring, ordering a wedding band online, sizing a surprise gift, or comparing international jewelry — type one value and every other standard appears instantly, or measure first and let the app do the rest.

Sizes are displayed in each system's standard increments — half sizes for US, whole numbers for EU and Asian systems — so you always see the nearest real size, not a raw decimal.

Features:
* Measure your ring size directly on your phone
* Real-time conversion as you type
* Favorite units for quick access
* Show or hide units you don't need
* Clean, ad-light interface
* Available in 13 languages
* Works fully offline — your data never leaves your device
