# 觀天氣 vs KNY地震速報

The clearest difference is rating: KNY地震速報 at 4.9 against 觀天氣's 4.5. KNY地震速報 also leads on update cadence (weekly vs every 2 months). 觀天氣's advantage is review sentiment (77% vs 57%) and ratings volume (64 vs 8). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

KNY地震速報 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: 觀天氣 has 64 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 77% of 觀天氣's written reviews are positive against 57% of KNY地震速報's, so the app with the better star average is not the one people write more warmly about.

觀天氣 ships an update every 2 months, KNY地震速報 weekly. Both last shipped on October 24, 2026.
