# 地震预警 vs 公文写作

The clearest difference is rating: 公文写作 at 5.0 against 地震预警's 1.9. 公文写作 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.6). 地震预警's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (30% vs 0%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 地震预警 sells 20 in-app purchases, starting at $1.99 per year and 公文写作 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

公文写作 holds the better App Store score, 5.0 against 1.9. That said, the two scores are not equally well evidenced: 地震预警 has 162 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of 地震预警's written reviews are positive against 0% of 公文写作's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
