# 倒数日 · Days Matter vs C Keyboard

The clearest difference is ads: C Keyboard at none against 倒数日 · Days Matter's shown. C Keyboard also leads on update cadence (every 6 days vs monthly) and iOS requirement (11.0 vs 15.0). 倒数日 · Days Matter's advantage is ratings volume (8.3K vs 3) and review sentiment (87% vs 70%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 倒数日 · Days Matter sells 11 in-app purchases, starting at $0.49 per month and C Keyboard sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

C Keyboard holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 倒数日 · Days Matter has 8.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 87% of 倒数日 · Days Matter's written reviews are positive against 70% of C Keyboard's, so the app with the better star average is not the one people write more warmly about.

倒数日 · Days Matter ships an update monthly, C Keyboard every 6 days. The most recent releases landed on October 25, 2026 and October 10, 2026 respectively.
