# Sentarm vs 有时闹钟

The clearest difference is rating: Sentarm at 4.2 against 有时闹钟's 1.0. Sentarm also leads on ratings volume (5 vs 1). 有时闹钟's advantage is review sentiment (69% vs 50%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sentarm sells 4 one-off in-app purchases and 有时闹钟 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Sentarm holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: Sentarm has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Sentarm's written reviews are positive against 69% of 有时闹钟's, so the app with the better star average is not the one people write more warmly about.

Sentarm ships an update weekly, 有时闹钟 every 8 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
