NMF.earth is a carbon diary & sustainable guide available for free for iOS and Android. Helping user to understand and reduce theirs carbon footprint, it was made after a successful Kickstarter.
More than 30 developers contributed to the app and is the app is available in 12 languages. The app uses Open Food Fact API for food product carbon emissions calculation.
This React Native application is built with Expo, Redux Toolkit and Typescript and has high code coverage using Github Action.
I've created a design system for the occasion and you can find it with the app design on Figma.
