# Duochang vs 海龜湯

The clearest difference is rating: 海龜湯 at 3.7 against Duochang's 2.3. Duochang's advantage is review sentiment (40% vs 0%) and monetization model (free vs freemium). On price, ratings volume, update cadence and ads there is nothing between them.

海龜湯 holds the better App Store score, 3.7 against 2.3. Both are backed by a comparable volume of ratings — 6 and 3 respectively.
