Hexmarrow: Firmware Lab
Intel HEX firmware desk
$0.99 · Designed for iPad. Not verified for macOS.
Inspect Intel HEX/S-record/UF2/ELF images with checksum validation—text notes, no shared atlas.
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
