### 4/5 — All your charts in one place

*2026-04-28*

That’s the goal and it’s a strong start. Convert easily between Imperial, metric and troy weights, various ring sizing systems, pi, and stone weights. That’s just the first page.


Only thing keeping this from 5 stars is the pro version isn’t a one time purchase. Yet 🤞

### 5/5 — Awesome App!!

*2026-04-27*

This is such an awesome app with great tools for goldsmiths! I really love the eternity band builder tool, but there’s so many more that I will be using! The app is loaded with essential everyday calculations and references for jewelers!! Thank you Ian for building this!

### 5/5 — Aaron - Goldsmith/Stone Setter

*2026-04-21*

I have been a goldsmith and stone setter of all types including micro pave and colored stone setting for 20 years and I have always battled with multiple tabs open, searching for conversions and thanks to my fellow Jeweler, “Ian”, now I can have it in one place and save time! Very satisfied! 

Thanks Ian!
