# 哈友会 vs 地震预警

The clearest difference is rating: 哈友会 at 3.1 against 地震预警's 1.9. 哈友会 also leads on in-app purchases (none vs 5) and ads (none vs shown). 地震预警's advantage is review sentiment (29% vs 0%) and ratings volume (163 vs 7). On price, update cadence and device support there is nothing between them.

Both are free to download. 地震预警 sells 5 in-app purchases, starting at $1.99 per year. 哈友会 asks for nothing beyond the download.

哈友会 holds the better App Store score, 3.1 against 1.9. That said, the two scores are not equally well evidenced: 地震预警 has 163 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 0% of 哈友会's written reviews are positive against 29% of 地震预警's, so the app with the better star average is not the one people write more warmly about.

哈友会 ships an update every 6 weeks, 地震预警 monthly. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
