# ChatEt vs 上下求索

The clearest difference is review sentiment: ChatEt at 100% against 上下求索's 0%. ChatEt also leads on update cadence (every 2 weeks vs every 6 weeks). 上下求索's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases).

Both are free to download. ChatEt sells 4 in-app purchases, starting at $2.99 per month and 上下求索 sells 5 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
