Jetzy - File Transfer

Send files (photos, videos, documents, folders, and text) between Android and iOS in seconds. No internet. No cloud. No account. Nothing else needed. Just two phones sending and receiving.

Jetzy moves files directly from one device to another over WiFi Direct, a local hotspot, or your LAN — whichever is fastest for the two phones in front of you. Nothing ever leaves the local link between your devices.

✨ Features

📦 Files of any size, any format — no 25 MB limits, no "unsupported file type" errors
📁 Send entire folders, kept intact
🖼️ Send photos and videos without messenger compression
📝 Send quick text snippets — passwords, addresses, URLs, notes
🔍 Pair by scanning a QR code, or discover peers on your local network
🔄 Secondary-QR reconnect — resume a dropped transfer without restarting
🌓 Light and dark themes
🌐 Localized UI
🎯 Responsive layout — scales cleanly on any screen size

🔒 Privacy you can verify, not just trust

Jetzy collects no data, contains no analytics, and talks to no remote servers. Ever. Every transfer is peer-to-peer. There is no backend — the developer doesn't run a single server that your phone talks to.

Because Jetzy is fully open source, you can verify every claim above. The code is public. Every byte, every protocol frame, every permission use is inspectable.

⚡ Built with Kotlin Multiplatform

Jetzy is built end-to-end with Kotlin Multiplatform and Compose Multiplatform — a single Kotlin codebase runs natively on Android and iOS. The result: identical behavior, identical UX, native performance.

🌍 Cross-platform by design

Android ↔ Android, iOS ↔ iOS, and Android ↔ iOS — all supported. On Android, Jetzy uses WiFi Direct or provisions a local hotspot. On iOS, it uses Apple's MultipeerConnectivity or joins the peer's WiFi.
