ReceptionRating · Positive reviews · Number of ratings

LotDate holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: LotDate has 231 ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 57% of HiddenTag(히든태그)'s written reviews are positive against 46% of LotDate's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HiddenTag(히든태그) ships an update every 8 days, LotDate every 4 days. The most recent releases landed on October 10, 2026 and October 11, 2026 respectively.
