# 文心 vs SundAi

The clearest difference is review sentiment: SundAi at 80% against 文心's 33%. SundAi also leads on rating (4.5 vs 2.6) and iOS requirement (13.0 vs 15.0). 文心's advantage is ratings volume (167 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 文心 sells 6 one-off in-app purchases and SundAi sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SundAi holds the better App Store score, 4.5 against 2.6. That said, the two scores are not equally well evidenced: 文心 has 167 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 33% of 文心's written reviews are positive against 80% of SundAi's.

Both ship on a similar rhythm, roughly every 2 weeks. Both last shipped on November 4, 2026.
