# 扣子AI vs 豆牙

The clearest difference is rating: 豆牙 at 4.5 against 扣子AI's 3.6. 豆牙 also leads on update cadence (daily vs every 3 months) and ratings volume (301 vs 15). 扣子AI's advantage is ads (none vs shown) and iOS requirement (13.0 vs 16). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. 扣子AI sells 3 in-app purchases, starting at $4.99 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.

豆牙 holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: 豆牙 has 301 ratings behind it against 15, so its average is the more settled of the two. Written reviews split almost evenly too, at 0% and 0% positive.

扣子AI ships an update every 3 months, 豆牙 daily. The most recent releases landed on August 1, 2026 and September 24, 2026 respectively.
