# 检查错别字 vs 小红查词

The clearest difference is monetization model: 检查错别字 at free with in-app purchases against 小红查词's subscription. 小红查词's advantage is update cadence (every 2 days vs monthly) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 检查错别字 sells 2 in-app purchases, starting at $1.99 per month and 小红查词 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
