I built EchoFlow because I wanted AI chat on Android to feel like it truly belongs on your phone, not like a web app placed inside an Android shell. It’s open-source, purely BYOK, and currently powered through OpenRouter. Your conversations are stored locally on your device, so you can still open and read past chats even when you’re offline. No tracking, no cloud inbox for your history, just your chats on your device. A big focus was the Android experience. Most AI apps feel like the same web UI with different branding, and many mobile apps copy the same iOS-style patterns. I wanted EchoFlow to feel fresh, fun, and Android-native, with Material Expressive design, springy animations, wallpaper-based theming, and a UI that feels connected to your device. The goal is for the app you use every day to feel built for you, rather than feeling like every other app. I’m also planning to support more AI providers beyond OpenRouter, and a native iOS app is coming too. I’d love your feedback on the design, local chat history, and what would make EchoFlow better for everyday AI use.
