## What it is
SFA is the official Android client for sing-box, a universal proxy platform. It provides a graphical interface for managing and running sing-box proxy configurations on Android devices.

## Use cases
- run sing-box proxy on android
- connect to proxy servers from my phone
- bypass internet censorship on android
- manage proxy configurations with a gui
- route traffic through vless or trojan on android

## When to choose
- you want an official, maintained Android frontend for sing-box
- you need a VPN-style app to route device traffic through sing-box
- you already use sing-box on desktop and want a mobile client

## When to avoid
- you need an iOS, desktop, or router client rather than Android
- you want a fork distributable on F-Droid under the same name (license forbids it)
- you need a proxy server rather than a client
