If you want a OpenRouter Android app that feels native, fast, and private, EchoFlow is built for you. It is an open-source OpenRouter client—a BYOK OpenRouter app where your key stays on your device and your chats stay in local storage.
Why use an OpenRouter client on mobile?
OpenRouter gives you one API for hundreds of models. A dedicated OpenRouter chat app on Android means you can use those models anywhere— not just at a desktop browser. EchoFlow is a mobile OpenRouter client with Material Design, offline chat history, and Android-native features like background Deep Research.
What EchoFlow adds beyond a basic client
- Local chat history — conversations stored on your phone (privacy details)
- Model switching — change models mid-chat (multi-model guide)
- Web search — connect models to live search providers
- Imagine — OpenRouter image generation in a separate creative workspace
- No account in EchoFlow — only your OpenRouter key, stored locally
Getting started
