# GRE Exam Practice vs AT

The clearest difference is ads: AT at none against GRE Exam Practice's shown. GRE Exam Practice's advantage is device support (3 vs 1) and iOS requirement (13.4 vs 16.4). On price and in-app purchases there is nothing between them.

Both are free to download. GRE Exam Practice sells 2 in-app purchases, starting at $1.99 per 7 days and AT sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
