## What it is
FengYunWeather is an open-source Android weather app written in Kotlin using MVX architecture with coroutines, OkHttp, Room, and Coil. It provides global daily and hourly forecasts, air quality data for Chinese cities, weather animations, widgets, and skin theming.

- view air quality index for chinese cities
- manage and search cities with fuzzy suggestions
- add a weather widget to the home screen
- learn android app development with kotlin and mvx

## When to avoid
- you need an iOS or desktop weather app
- you cannot obtain a HeWeather API key or AMap location key
- you want to reuse the code in a commercial closed-source product (GPL-3.0 forbids it)
