Verdict
倒数日 · Days Matter and 格式转换 both sit at 4.8 stars, but that hides the real split: 88% of 倒数日 · Days Matter's written reviews are positive against 38% of 格式转换's. 倒数日 · Days Matter also leads on ratings volume (8.3K vs 3) and update cadence (every 3 weeks vs every 4 months). On price, rating, ads and in-app purchases 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
Both are free to download. 倒数日 · Days Matter sells 10 in-app purchases, starting at $0.49 per month and 格式转换 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
格式转换 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: 88% of 倒数日 · Days Matter's written reviews are positive against 38% of 格式转换'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 every 3 weeks, 格式转换 every 4 months. Both last shipped on November 13, 2026.
