# CTCAE 5 Pro vs CRA Assistant

The clearest difference is ratings volume: CTCAE 5 Pro at 41 against CRA Assistant's 1. On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CTCAE 5 Pro sells 2 in-app purchases, starting at $1.99 per month and CRA Assistant sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
