MAC Vendor Lookup

Offline OUI / vendor lookup

Free · Designed for iPad. Not verified for macOS.

v1.2: Tip Jar fixed, new Inventory tab with CSV/Text export from any tag, and a fully offline OUI database with 35,000+ vendors. No accounts. No tracking. No ads. MAC Vendor Lookup is the fastest way to identify the manufacturer behind any MAC address — fully offline, with no accounts, no tracking, and no ads. Paste any MAC address and instantly see the vendor, OUI block, registry, and assignment range. The full IEEE OUI database (35,000+ vendors) is bundled with the app and works without an internet connection. Use the camera scanner to read MAC addresses off router labels and device stickers, or paste a wall of text from a log file and let the bulk extractor pull every address it can find. FEATURES • Instant offline lookup — no network calls, no waiting • Bundled IEEE OUI database, fully up to date • Camera scanner with on-device OCR • Bulk extraction from pasted text, logs, or imported files • History with notes, tags, and favorites • Insights view summarizing your most-seen vendors • Home-screen widget for recent lookups • Share Sheet extension — extract MACs from any app • Shortcuts & App Intents — automate lookups from anywhere on iOS • iPad and iPhone, light and dark mode, full Dynamic Type and VoiceOver PRIVACY This app is fully offline. No accounts. No analytics. No tracking. No third-party SDKs. Your lookups, notes, and tags never leave your device. TIP JAR The app is free. If it earns its keep on your home lab, network closet, or pen-test rig, an optional tip is appreciated. Tips unlock nothing — everything in the app is already yours. Made with care in the lab.

• New: export your inventory (or any tag) as CSV or plain text from the share button • Renamed History to Inventory — better fit for the catalog of MACs you're tracking • Fixed the Tip Jar — purchases now complete properly on iOS 17+ • Reliable StoreKit transaction handling for interrupted and Ask-to-Buy purchases • Quieter logs: silenced spurious App Group warnings on first launch Thanks for using MAC Vendor Lookup!
