# CT vs Learn X

The clearest difference is rating: CT at 4.5 against Learn X's 1.0. CT also leads on in-app purchases (none vs 3) and ratings volume (12 vs 1). On price and ads there is nothing between them.

Both are free to download. Learn X sells 3 in-app purchases, starting at $6.99 per month. CT asks for nothing beyond the download.

CT holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: CT has 12 ratings behind it against 1, so its average is the more settled of the two.
