# CA AMP vs DSI

The clearest difference is rating: CA AMP at 4.0 against DSI's 1.0. CA AMP also leads on ratings volume (6 vs 1) and iOS requirement (11.0 vs 13). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CA AMP holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: CA AMP has 6 ratings behind it against 1, so its average is the more settled of the two.
