About

QR

Read full description

QR-log Bridge transfers files between screens and Apple devices through animated QR streams. It is designed for situations where no shared network, cloud service, cable, AirDrop, or removable storage is available. Receive a QR stream live with the camera or reconstruct a transfer from a recorded video. Choose a file or photo on your iPhone or iPad and present it as a fullscreen QR stream for another compatible receiver. ## Receive Files - Scan animated 1x1 and 2x2 QR streams. - Reconstruct missing data using recovery information embedded in compatible streams. - Decode recorded QR streams from Photos, Files, or locally captured videos. - Automatically record and process compatible high-speed streams. - Use longer automatic recording windows for compatible V9 streams, up to two minutes. - Verify completed payloads and restore their original filenames. - Monitor transfer progress and live capture quality. ## Send Files - Choose one local file or photo. - Generate V6 or high-throughput V9 streams directly on the device. - Adjust V9 recovery overhead from 10% to 50%. - Select stream timing from 20 to 60 FPS or use the 50 ms, 30 FPS, and 60 FPS presets. - Present the generated stream in fullscreen without creating an intermediate upload or cloud copy. ## Local By Design Encoding, camera analysis, reconstruction, and integrity verification run locally. No account or external server is required. Received files and captured videos remain in the app's local storage until you share or delete them. QR-log Bridge is intended for technical file transfer. Successful performance depends on the display, camera, lighting, distance, selected stream speed, and payload size.
