Paperclip

Minimal, monochrome, friends-only emoji presence app. No chat — just vibes.

iOS: github.com/ejfox/paperclip (SwiftUI) Android: github.com/ejfox/paperclip-android (Kotlin / Jetpack Compose) Backend: Supabase (cross-platform realtime sync)

Concept

You broadcast one emoji to your friends. That's it. No messages, no feeds, no algorithms. Your friends see your vibe. You see theirs. If someone's been 🔥 all week and suddenly goes 😴, you know to check in.
