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 app's own text says: "Format memory"
This observation has not cleared the required evidence standard.
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.

Advancement or competition is gated behind spending money rather than playing.

The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.

The app's own copy describes working without a connection — offline mode, downloading for offline use, or content saved for later. Shown because readers filter on it; it is a feature, not a fairness property, and never counts for or against an app.

No review-based observation is published in this assessment. That does not establish that reviewers had no problems.
“Not assessed” means we could not measure it. It is never a zero and never a pass.

nfc-tools-apple-1252962749Assessed 2026-10-30 from 400 user reviews, the app's package and the store listing.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
This assessment is produced automatically. Five independent signals are read — user reviews, SDKs in the app package, the app's own on-screen text, the app manifest and the store listing — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every recurring plan the store lists is named as weekly, the term read from the purchase names, with a list cut off at the store’s 10-item maximum not assessed; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
