Verdict
倒数日 · Days Matter and 药研社 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 0% of 药研社's. 倒数日 · Days Matter also leads on ratings volume (8.3K vs 1) and device support (4 vs 2). 药研社's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, rating and update cadence 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. 药研社 asks for nothing beyond the download.
药研社 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 1, 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 0% of 药研社'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, 药研社 every 5 weeks. The most recent releases landed on November 11, 2026 and November 6, 2026 respectively.
