# 小鱼短信 vs Read Copilot

The clearest difference is update cadence: Read Copilot at every 6 days against 小鱼短信's monthly. 小鱼短信's advantage is ratings volume (31 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 小鱼短信 sells 3 in-app purchases, starting at $0.99 per month and Read Copilot sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Read Copilot holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 小鱼短信 has 31 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

小鱼短信 ships an update monthly, Read Copilot every 6 days. The most recent releases landed on October 12, 2026 and October 24, 2026 respectively.
