# Summary vs 豆牙

The clearest difference is review sentiment: Summary at 100% against 豆牙's 0%. Summary also leads on rating (4.7 vs 4.5) and iOS requirement (13.0 vs 16). 豆牙's advantage is update cadence (daily vs every 6 days) and ratings volume (301 vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Summary sells 10 in-app purchases, starting at $8.99 per 7 days and 豆牙 sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Summary holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 豆牙 has 301 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 100% of Summary's written reviews are positive against 0% of 豆牙's.

Summary ships an update every 6 days, 豆牙 daily. The most recent releases landed on September 10, 2026 and September 24, 2026 respectively.
