# 北大法宝 vs CAJ云阅读

The clearest difference is update cadence: CAJ云阅读 at every 6 days against 北大法宝's every 5 weeks. CAJ云阅读 also leads on iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 北大法宝 sells 7 one-off in-app purchases and CAJ云阅读 sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
