# Earth School vs CPHQ Study Guide

The clearest difference is iOS requirement: Earth School at 10.0 against CPHQ Study Guide's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Earth School sells 1 one-off in-app purchase and CPHQ Study Guide sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
