# TerraWatch vs Earthquake

The clearest difference is in-app purchases: Earthquake at none against TerraWatch's 1. Earthquake also leads on iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. TerraWatch sells 1 one-off in-app purchase. Earthquake asks for nothing beyond the download.
