About this app

Made for a clear purpose.

Hexmarrow is an offline firmware inspection desk for Intel HEX and related formats.

Validate records and checksums, decode addresses, review overlaps/gaps, and study a text Firmware Notes set. Build 3 removes all shared atlas imagery so this binary no longer resembles plate-pack gallery apps.

Built for embedded engineers—not a lighthouse game or chemistry ledger.

What you can do • HEX/S-record/UF2/ELF inspection • Memory map and checksum validation • Bundled sensor-node.hex sample • Text-only firmware notes (no image atlas) • Fully offline; no login
