AuRatio
Coffee ratio calculator. Brew better at home.
Download on the App Store Google Play — coming soon
AuRatio is a small, focused tool for home coffee brewing. Punch in your coffee weight and target ratio; the app gives you the water and helps you save the recipes that work.
I built it because I wanted a calculator that did one thing well — no ads, no signup, just a clean interaction. It’s also been a way to keep my mobile chops sharp outside of work.
The app is bilingual (English and Arabic) with full RTL support, and it includes QR-based recipe sharing so you can hand a recipe to a friend without typing it twice.
