Verdict

The call

The clearest difference is review sentiment: LibTalk at 50% against 格式鱼's 0%. LibTalk also leads on update cadence (every 3 weeks vs every 2 months) and ratings volume (5 vs 1). 格式鱼's advantage is rating (4.0 vs 3.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. 格式鱼 sells 5 in-app purchases, starting at $2.99 per 7 days and LibTalk sells 7 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

格式鱼 holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: LibTalk has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of 格式鱼's written reviews are positive against 50% of LibTalk's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

格式鱼 ships an update every 2 months, LibTalk every 3 weeks. Both last shipped on November 4, 2026.
