# Trailix vs CPP Exam Prep

The clearest difference is device support: CPP Exam Prep at 2 against Trailix's —. Trailix's advantage is iOS requirement (15.1 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Trailix sells 1 in-app purchase, starting at $3.69 per month and CPP Exam Prep sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
