About this app

Zapp is the fastest way to send files between Android devices no internet connection, no cables, and no size limits.

Using Wi-Fi Direct, Zapp creates a direct connection between two phones and transfers files at high speed, even when there's no Wi-Fi network or mobile data available. Whether you're sharing a few photos or moving gigabytes of video, Zapp gets it there in seconds.

WHY ZAPP

⚡ Works completely offline
No internet, no shared Wi-Fi network, and no mobile data required. Zapp creates its own direct Wi-Fi Direct connection between devices.

📁 Send any file type
Photos, videos, music, documents, and even installed apps (APKs) — if it's on your phone, Zapp can send it.

👥 Share with multiple devices at once
Group sharing sends the same files to several nearby phones in parallel, over a single hotspot — perfect for sharing with a group of friends at once.

🚀 Built for speed
Real-world tests show a 1.45 GB file transferring in under a minute over Wi-Fi Direct.

🔒 Private by design
Files move directly between devices. Nothing is uploaded to or stored on any server — Zapp never sees the content you send or receive.

🎯 Simple to use
Scan a QR code or pick a nearby device, choose your files, and send. No account, no sign-up, no complicated setup.

HOW IT WORKS

1. Open Zapp and tap Send or Receive
2. Connect two devices via QR code or the nearby device list
3. Pick your files — photos, videos, apps, or any document
4. Transfer instantly over a direct, offline connection

PREMIUM

Zapp is free to use, supported by ads. Prefer an ad-free experience? Unlock Zapp Premium with a single one-time purchase — no subscriptions, ever.

PERMISSIONS

Zapp only asks for what a transfer actually needs: camera (to scan QR codes), location and nearby Wi-Fi devices (required by Android for Wi-Fi Direct discovery), notifications (for transfer progress), and file/media access (to pick what you send). Full details are in our Privacy Policy.

Download Zapp today and start sharing files the fast, offline way.
