Verdict

The call

The clearest difference is review sentiment: Coin Chat at 65% against 默信's 17%. Coin Chat also leads on update cadence (every 6 days vs fortnightly) and device support (4 vs 2). 默信's advantage is rating (2.4 vs 1.0) and ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 默信 sells 10 one-off in-app purchases and Coin Chat sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

默信 holds the better App Store score, 2.4 against 1.0. That said, the two scores are not equally well evidenced: 默信 has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 17% of 默信's written reviews are positive against 65% of Coin Chat's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

默信 ships an update fortnightly, Coin Chat every 6 days. Both last shipped on November 3, 2026.
