TrueTag is a fast NFC tag reader, writer and scanner, with no ads, no account and no internet access. Everything runs on your phone, works offline and stays private.

What it does

• Read any tag. Links, text, Wi-Fi, contacts and more, plus the tag's identity (serial number, chip technologies, ATQA/SAK), even when a tag carries no readable data.
• Check it is genuine. TrueTag inspects the chip's version fingerprint and flags likely clones of NTAG stickers.
• Write in seconds. Links, text, Wi-Fi details, contacts, phone numbers, email, SMS and locations, with starter templates and a batch mode for many tags.
• Keep a tag library. Save scans and writes, search them, write one again with a tap, and export or import the whole library as plain JSON.
• Power tools. Duplicate a tag, view its raw memory, look up common chips offline and share a clean report of any tag.

Private by design

• No internet permission: the app cannot send your data anywhere
• No account, no sign-up, no analytics, no tracking
• No ads, and free
• Works fully offline
