# 维鉴 vs 成分喵

The clearest difference is rating: 成分喵 at 4.5 against 维鉴's 3.9. 成分喵 also leads on in-app purchases (none vs 4). 维鉴's advantage is ads (none vs shown) and review sentiment (90% vs 67%). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. 维鉴 sells 4 one-off in-app purchases. 成分喵 asks for nothing beyond the download.

成分喵 holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 15 and 17 respectively. Written reviews complicate that: 90% of 维鉴's written reviews are positive against 67% of 成分喵's, so the app with the better star average is not the one people write more warmly about.

维鉴 ships an update every 2 weeks, 成分喵 fortnightly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
