# 柠檬轻断食 vs 吃有数

The clearest difference is review sentiment: 吃有数 at 98% against 柠檬轻断食's 38%. 吃有数 also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.7). 柠檬轻断食's advantage is ratings volume (590 vs 3) and iOS requirement (13.0 vs 15.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 柠檬轻断食 sells 10 in-app purchases, starting at $6.99 per month 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: 柠檬轻断食 has 590 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 38% of 柠檬轻断食's written reviews are positive against 98% of 吃有数's.

柠檬轻断食 ships an update fortnightly, 吃有数 weekly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
