RedeemDeck vs Hexmarrow

RedeemDeck is a free, open-source, local-first offer-code manager for Apple platform developers. Import offer-code and promotional-code CSV exports from App Store Connect, organize codes by app and offer, and retrieve exactly the quantity you need—without maintaining another spreadsheet. BUILT FOR THE DISTRIBUTION WORKFLOW • Organize multiple apps, subscriptions, discounts, campaigns, and other offers • Keep Available, Pending, Sent, and Expired codes clearly separated • Select the earliest-expiring inventory automatically • Copy complete codes or ready-to-redeem links with one tap • Share a prepared selection with the system share sheet • Create polished QR posters with app artwork, expiration details, and a personal greeting • Search, filter, edit, archive, and restore codes from a dedicated management view • Schedule optional local expiration reminders • Export and restore complete backups when you choose • Use the app in English or Simplified Chinese on iPhone and iPad PRIVATE BY DESIGN No account. No advertising. No analytics or tracking. No developer-operated backend. Your library stays in the app's local sandbox. Network access is limited to public App Store metadata and artwork lookup, plus links that you explicitly open. “Sent” is a local workflow state. It does not claim that Apple has confirmed a code as redeemed.

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
