# 小鱼短信 vs 真好算

小鱼短信 and 真好算 both sit at 4.8 stars, but that hides the real split: 100% of 小鱼短信's written reviews are positive against 67% of 真好算's. 小鱼短信 also leads on ratings volume (31 vs 3) and iOS requirement (15.1 vs 17.0). On price, rating, update cadence 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 真好算 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

真好算 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 complicate that: 100% of 小鱼短信's written reviews are positive against 67% of 真好算's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 9, 2026 and September 23, 2026 respectively.
