# 海思分级阅读 vs 火龙果AI

The clearest difference is ads: 海思分级阅读 at none against 火龙果AI's shown. 火龙果AI's advantage is update cadence (weekly vs every 4 months) and iOS requirement (12.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 海思分级阅读 sells 2 one-off in-app purchases and 火龙果AI sells 7 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

海思分级阅读 ships an update every 4 months, 火龙果AI weekly. Both last shipped on October 16, 2026.
