ReceptionRating · Positive reviews · Number of ratings

Smart NFC Tools holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Smart NFC Tools has 480 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 77% of tra cứu PHONG THỦY's written reviews are positive against 30% of Smart NFC Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

tra cứu PHONG THỦY ships an update every 7 months, Smart NFC Tools weekly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
