# Hiddentag COP vs LotDate

The clearest difference is in-app purchases: Hiddentag COP at none against LotDate's 3. Hiddentag COP also leads on review sentiment (79% vs 47%) and iOS requirement (13.4 vs 18.0). LotDate's advantage is ads (none vs shown) and rating (4.7 vs 4.5). On price, update cadence 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 COP asks for nothing beyond the download.

LotDate holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: LotDate has 335 ratings behind it against 40, so its average is the more settled of the two. Written reviews complicate that: 79% of Hiddentag COP's written reviews are positive against 47% of LotDate's, so the app with the better star average is not the one people write more warmly about.

Hiddentag COP ships an update weekly, LotDate every 4 days. Both last shipped on November 6, 2026.
