GapRelay: File Transfer

Move files and messages through the routes your devices actually have—without requiring a GapRelay account or a transfer cloud.

OFFLINE TRANSFER
• Broadcast files as resilient changing QR frames.
• Use Nearby routes when both devices support a compatible direct connection.
• Record QR Video on one device and decode it later on another.

SIGNALS AND TAGS
• Translate and practice Morse with light, sound and touch.
• Generate and inspect Sonic, SSTV and DTMF signals.
• Read, inspect and write compatible NDEF NFC tags.

VERIFY BEFORE YOU RELEASE
• Check file integrity with cryptographic hashes.
• Use optional end-to-end encryption and explicit pairing verification.
• Inspect received links, contacts, locations and files before acting on them.

HONEST LIMITS
Hardware and operating-system support varies. GapRelay shows available routes and offers fallbacks where practical. QR Video reception is free; some creation and security tools require Pro. The free version may show ads only on eligible non-sensitive screens. Purchases stay with the Apple or Google account and platform where they were made.

Core transfers can work without Internet. Files are processed on your device.
