# 清史数据库 vs AI肌肤检测

The clearest difference is update cadence: 清史数据库 at every 4 days against AI肌肤检测's every 3 months. AI肌肤检测's advantage is review sentiment (100% vs 80%) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 清史数据库 sells 2 in-app purchases, starting at $9.99 per year and AI肌肤检测 sells 3 in-app purchases, starting at $5.00 per 7 days. Whichever you choose, the download price is not the number that matters.

清史数据库 ships an update every 4 days, AI肌肤检测 every 3 months. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
