Swapio: Offline File Transfer

Swapio sends photos, videos, music, apps and any other file straight from one phone to another device over Wi-Fi. No internet, no mobile data, no cables, no server in between. HOW IT WORKS • Tap Send, pick your files, then scan the QR code on the receiving phone. Or tap Receive to show a QR code for the sender. • The two phones connect through a local hotspot, Wi-Fi Direct or the Wi-Fi network you already use. • A phone nearby on the same Wi-Fi shows up under "Nearby". Tap it to send. WORKS WITH EVERY DEVICE • Android to Android: install Swapio on both phones. • iPhone, iPad, Windows, Mac, Linux: the other device only needs a browser. Scan the QR code or type the 6-digit code. Nothing to install. The browser can also upload files back to your phone. FEATURES • Two-way transfer on one connection. Tap "Send more" without reconnecting. • Send photos, videos, music, documents, whole folders (structure kept) and apps installed on your phone. • See progress for each file, cancel any file, keep transferring in the background with a progress notification. • Every received file is checked for integrity before it is marked done. • Send from any app through Android's Share button. • History by day. Open, share or delete received files. • Invite friends even without internet: they scan a QR code to download the app over Wi-Fi, or you send them the installer. • Light and dark themes, English and Vietnamese. PRIVACY • No account. • Files go straight between devices and never pass through a server. • QR codes work once. A nearby device that wants to send you files needs your approval. • The web share page is protected by a 6-digit code and temporarily locks after repeated wrong tries. • Delete only removes files you received, never the original on the sender's phone. PERMISSIONS AND WHY • Nearby Wi-Fi devices (Android 13+) or Location (Android 12 and below): to create and join the Wi-Fi link between two phones. Swapio does not read or store your location. • Camera: to scan QR codes. Optional, you can use "Nearby" instead. • Photos, videos, music: so you can pick files to send. • Notifications: to show transfer progress. • Install apps: only when you choose to install an app you received. GOOD TO KNOW • Requires Android 8.0 or newer and Wi-Fi. • Speed depends on both phones and their Wi-Fi.
