# HiddenTag(히든태그) vs LotDate

The clearest difference is rating: LotDate at 4.7 against HiddenTag(히든태그)'s 3.3. LotDate also leads on ads (none vs shown) and update cadence (every 4 days vs every 8 days). HiddenTag(히든태그)'s advantage is in-app purchases (none vs 3) and review sentiment (57% vs 46%). On price and device support there is nothing between them.

Both are free to download. LotDate sells 3 in-app purchases, starting at $2.99 per month. HiddenTag(히든태그) asks for nothing beyond the download.

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.

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.
