# 地震预警中心 vs 手机管家

The clearest difference is rating: 手机管家 at 4.5 against 地震预警中心's 3.0. 手机管家 also leads on ratings volume (281 vs 1) and iOS requirement (12.0 vs 15.6). 地震预警中心's advantage is in-app purchases (none vs 2) and review sentiment (45% vs 14%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. 手机管家 sells 2 in-app purchases, starting at $9.99 per 7 days. 地震预警中心 asks for nothing beyond the download.

手机管家 holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: 手机管家 has 281 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 45% of 地震预警中心's written reviews are positive against 14% of 手机管家's, so the app with the better star average is not the one people write more warmly about.

地震预警中心 ships an update every 6 months, 手机管家 every 3 months. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
