# 健康计步 vs 地震预警

The clearest difference is device support: 健康计步 at 2 against 地震预警's —. 健康计步 also leads on iOS requirement (11.0 vs 13.0). On price and in-app purchases there is nothing between them.

Both are free to download. 健康计步 sells 1 in-app purchase, starting at $2.99 per month and 地震预警 sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
