Verdict
The clearest difference is ratings volume: 须臾 at 456 against Time Plan's 3. 须臾 also leads on update cadence (every 3 days vs every 2 weeks). Time Plan's advantage is rating (5.0 vs 4.7). On price, review sentiment, 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. 须臾 sells 1 one-off in-app purchase and Time Plan sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Time Plan holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 须臾 has 456 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 84% of 须臾's written reviews are positive against 76% of Time Plan's, so the app with the better star average is not the one people write more warmly about.
须臾 ships an update every 3 days, Time Plan every 2 weeks. Both last shipped on November 6, 2026.
