Everything runs on your phone, works offline and stays private.

READ ANY TAG
Tap any NFC tag and see exactly what it is. TrueTag decodes NDEF records (links, text, Wi-Fi, contacts and more) and always shows the tag's identity — serial number (UID), chip technologies, ATQA/SAK — even when a tag carries no readable data. No more "empty tag" dead ends.

CHECK IT'S GENUINE
Bought NTAG stickers online? TrueTag inspects the chip's version fingerprint and flags likely clones, so you know whether you got genuine chips or lookalikes.

WRITE IN SECONDS
Write links, plain text, Wi-Fi credentials, contacts, phone numbers, email, SMS and locations. Starter templates get common jobs done fast — including an emergency info (ICE) tag. Need many tags? Batch mode programs a whole stack in one session, and each tag is written exactly once even if you present it twice.

YOUR TAG LIBRARY
Save any scan or write to a local library: favorites, search, and one-tap "write this again". Export and import the whole library as plain, readable JSON — your data is never locked in.

POWER TOOLS
• Duplicate a tag: read one, write it to a fresh tag
• Memory viewer: raw hex dump of a tag's memory, exportable
• Chip reference: offline guide to common NFC chips — capacity, features, compatibility
• Tag report: share a clean, complete report of any tag

PRIVATE BY DESIGN
• No internet permission — the app is technically unable to send your data anywhere
• No account, no sign-up, no analytics, no tracking
• No ads. Free.
• Works fully offline

MADE TO BE CALM
Seven hand-tuned themes with live previews, light and dark modes, smooth motion, and a dedicated high-contrast style. Full TalkBack support.

WORKS WITH
NTAG 213 / 215 / 216 and other NDEF-formatted tags, plus identity info for MIFARE Classic, Ultralight and other NfcA/B/F/V chips. An NFC-capable phone is required.
