# 地震预警 vs Screen Time Control

The clearest difference is device support: Screen Time Control at 2 against 地震预警's —. 地震预警's advantage is iOS requirement (13.0 vs 16). On price and in-app purchases there is nothing between them.

Both are free to download. 地震预警 sells 3 in-app purchases, starting at $9.99 per month and Screen Time Control sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
