Transfqr

Transfqr sends files from one phone to another using light. Pick anything up to 50 MB - a photo, a PDF, a voice memo, a ZIP - and the app streams it as live QR codes on your screen. Point the other phone's camera at it and the file rebuilds itself in seconds. Works on a plane, in a basement, off-grid. No internet, no accounts, no cloud. HOW IT WORKS 1. SEND - open Transfqr, tap "Send a file", pick anything from your library. 2. WATCH - Transfqr breaks the file into fountain-coded chunks and broadcasts them as QR codes, around 12 frames per second. The lighthouse mascot blinks while broadcasting. 3. CATCH - on the other phone, open Transfqr, tap "Catch a file", aim the camera at the sender. Progress fills as chunks arrive. Done when the bar is full. PRIVACY BY DESIGN - No server. There is no Transfqr backend. Files never leave the two devices. - No account. No email, phone number, or identifier required. - Camera permission is used only to scan QR codes from the sender. - Storage permission writes the received file to your library. - Anonymous analytics and crash reporting are opt-in, both anonymous, both toggleable in Settings. WHAT YOU CAN SEND - Photos and videos from your library - PDFs, ZIPs, voice memos, documents, anything else under 50 MB - Multiple files in sequence (one transfer at a time) WHEN IT SHINES - Sending a file to someone with no Wi-Fi or cellular signal - Cross-platform transfers (iPhone to Android, no AirDrop dependency) - Privacy-sensitive contexts (no cloud trail, no metadata in third-party servers) - Anyone tired of "upload to cloud, send link, wait for download" Light. Local. Yours.
