# 每日减脂 vs 吃有数

The clearest difference is rating: 吃有数 at 5.0 against 每日减脂's 4.7. 吃有数 also leads on update cadence (weekly vs every 3 weeks). 每日减脂's advantage is ratings volume (29 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. 每日减脂 sells 7 in-app purchases, starting at $9.99 per 3 months and 吃有数 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

吃有数 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 每日减脂 has 29 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 98% and 98% positive.

每日减脂 ships an update every 3 weeks, 吃有数 weekly. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
