PromoKit vs Syntex

PromoKit helps app developers organize App Store offer-code campaigns without spreadsheet busywork. Import offer-code CSVs from App Store Connect, group codes by app and product, and share the next available code when a reviewer, tester, creator, or customer needs one. PromoKit can send code text through the iOS share sheet, copy a code, or create a branded QR share card that opens the redeem flow. Keep campaign history tidy as codes move. Mark codes as shared, record recipient names, set expiry dates, separate expired offers, and export CSVs with usage state preserved. Your code lists stay under your control. PromoKit stores campaign state in iCloud Documents when available, with a local Application Support fallback, and does not include advertising, third-party analytics, or tracking SDKs. Features: - Import App Store Connect offer-code CSVs - Organize multiple apps, products, and offers - Share, copy, or QR-share the next available code - Track recipients, shared dates, and remaining inventory - Mark codes used individually or in bulk - Set offer expiry dates and group expired offers - Export CSVs with sharing history preserved - Use light, dark, or system appearance
