# 私密相册 vs 体重管理

The clearest difference is update cadence: 体重管理 at every 3 days against 私密相册's every 2 weeks. 私密相册's advantage is iOS requirement (12.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 私密相册 sells 1 in-app purchase, starting at $4.99 per 7 days and 体重管理 sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

私密相册 ships an update every 2 weeks, 体重管理 every 3 days. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
