blastQR is an open-source file transfer app that works completely offline. Data is transferred through sequences of QR codes displayed on a sender device and scanned by a receiver device's camera.
It's fast enough for simple everyday picture and file transfers, and it's especially useful for air-gapped systems (computers that are completely cut off from any network). Transfers can optionally be encrypted with a password to prevent interception.
