# Silicon Evolution vs Kardashev

The clearest difference is rating: Silicon Evolution at 5.0 against Kardashev's 4.8. Kardashev's advantage is monetization model (ad-supported vs free with in-app purchases) and ratings volume (8 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Silicon Evolution sells 1 one-off in-app purchase and Kardashev sells 1 one-off in-app purchase. 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: Kardashev has 8 ratings behind it against 1, so its average is the more settled of the two.
