# 轻食记 vs 吃有数

The clearest difference is monetization model: 吃有数 at free against 轻食记's freemium. 吃有数 also leads on update cadence (weekly vs every 3 weeks). 轻食记's advantage is ratings volume (85 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 轻食记 sells 7 in-app purchases, starting at $3.99 per 7 days and 吃有数 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for 轻食记 against 5.0 for 吃有数. That said, the two scores are not equally well evidenced: 轻食记 has 85 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 99% and 98% positive.

轻食记 ships an update every 3 weeks, 吃有数 weekly. Both last shipped on October 28, 2026.
