NFC Tools can read and write your NFC tags with a simple and lightweight user interface. By passing your device near an NFC chip, you can read the data it contains and interact with the content. The "Read" section allows you to see data such as: - the maker of the tag - the type of tag (ex : Mifare Ultralight, NTAG213) - the norm of the tag (ex : NFC Forum Type 2) - the available technology (ex: NFC A) - its serial number (ex : 04:85:c8:5a:40:2b:80) - the size of the tag and of the data on it - if you can write on the tag - all the data on the tag (NDEF format) NFC Tools can record standard information on your tags which will be compatible with any NFC device. For instance, you can store a VCARD to share your contact details easily, open an URL, share a phone number or even a geolocation.

Verdict
The clearest difference is review sentiment: Keyless Authenticator at 95% against NFC Tools's 51%. Keyless Authenticator also leads on in-app purchases (none vs 1). NFC Tools's advantage is rating (4.6 vs 2.6) and ratings volume (14K vs 5). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. NFC Tools sells 1 one-off in-app purchase. Keyless Authenticator asks for nothing beyond the download.
NFC Tools holds the better App Store score, 4.6 against 2.6. That said, the two scores are not equally well evidenced: NFC Tools has 14K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 51% of NFC Tools's written reviews are positive against 95% of Keyless Authenticator's, so the app with the better star average is not the one people write more warmly about.
NFC Tools ships an update every 3 weeks, Keyless Authenticator every 5 weeks. The most recent releases landed on October 12, 2026 and October 7, 2026 respectively.
