# Silicon Evolution vs Ironhold

The clearest difference is ratings volume: Ironhold at 6 against Silicon Evolution's 1. Ironhold also leads on device support and iOS requirement (15.1 vs 26.2). On price, rating and in-app purchases there is nothing between them.

Both are free to download. Silicon Evolution sells 1 one-off in-app purchase and Ironhold sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Silicon Evolution holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Ironhold has 6 ratings behind it against 1, so its average is the more settled of the two.
