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. The "Write" section let you record standardised data such as: - a simple text - a link to a website - an email - a contact - a phone number - a predefined text message - an address or geolocation - a WiFi or Bluetooth configuration - personalised data - and more... The write function allows you to add as much data as you wish. This way you can record large quantities of information on your tag. The app also allows you to save the contents of your chip for later access. NFC Tools has been tested with the following NFC tags: - NTAG 203, 210, 210u, 212, 213, 213TT, 215, 216, 413 DNA, 424 DNA - Ultralight, Ultralight C, Ultralight EV1 - ICODE SLI, SLI-S, SLIX, SLIX-S, SLIX-L, SLIX2, DNA - DESFire EV1, EV2, EV3 - ST25TV, ST25TA - Felica If you encounter any problem, don’t hesitate to contact us. Notes: - Compatible from iPhone 7. - Use the "compatibility" mode to read/write Mifare Classic tags.

Verdict
The clearest difference is rating: NFC Tools at 4.6 against GCTools's 3.1. NFC Tools also leads on ratings volume (14K vs 13) and chart position (#148 vs unranked). GCTools's advantage is iOS requirement (9.2 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. GCTools sells 7 one-off in-app purchases and NFC Tools sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
NFC Tools holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: NFC Tools has 14K ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 40% of GCTools's written reviews are positive against 50% of NFC Tools's.
GCTools ships an update monthly, NFC Tools every 3 weeks. The most recent releases landed on September 27, 2026 and September 29, 2026 respectively.
