# Brain Sharp vs ChessBased

The clearest difference is rating: Brain Sharp at 4.7 against ChessBased's 4.0. Brain Sharp also leads on ratings volume (57 vs 1) and iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brain Sharp sells 1 one-off in-app purchase and ChessBased sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Brain Sharp holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Brain Sharp has 57 ratings behind it against 1, so its average is the more settled of the two.
