# 轻牛健康 vs 生酮减肥

On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 生酮减肥 sells 6 one-off in-app purchases. 轻牛健康 asks for nothing beyond the download.

轻牛健康 ships an update fortnightly, 生酮减肥 every 2 months. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
