# 黑耳 vs 体重管理

The clearest difference is ads: 体重管理 at none against 黑耳's shown. 体重管理 also leads on update cadence (every 3 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 黑耳 sells 9 one-off in-app purchases 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.

黑耳 ships an update every 2 months, 体重管理 every 3 days. The most recent releases landed on October 18, 2026 and October 1, 2026 respectively.
