# 地震 vs 地震预警

The clearest difference is rating: 地震 at 4.7 against 地震预警's 4.5. 地震 also leads on device support (3 vs 1). 地震预警's advantage is ratings volume (36 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 地震 sells 1 one-off in-app purchase and 地震预警 sells 5 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

地震 holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 地震预警 has 36 ratings behind it against 3, so its average is the more settled of the two.

地震 ships an update every 2 months, 地震预警 every 5 weeks. The most recent releases landed on August 24, 2026 and September 22, 2026 respectively.
